ABSTRACT - The degree of tolerance to aluminum of the corn variety "Dentado Composto" was related to of a tolerant variety "Cateto Colombia 96/71", and a susceptible one "Cateto Al 20268", by comparing the growth of their root systems in aqueous media with and without calcium and aluminum. The experimental design used was a 3 x 2 factorial in random blocks the following parameters were studied: depth of the main root in the solution, number and total lenght of seminal roots, pH variations in the solution and morphological aspects of the root system during 10 days of experiment. "Dentado Composto" showed intermediate tolerance compared to "Cateto Colombia 96/71" and "Cateto Al 20268", which demonstrated their respective tolerance and susceptibility. Further reasearch should be conducted with "Dentado Composto" in relation to its aluminum tolerance, using lower aluminum and/or higher calcium concentrations. In this case, toxicity symptoms could be less evident and the variety would be considered as viable in a breeding program aiming at the development of aluminum tolerant varieties to be used in areas where mechanical and economical aspects make it unfeasible to lime the soil in order to overcome production limitations imposed by aluminum toxicity.

ABSTRACT - Taxonomic and ecological studies were carried out on diatoms from the continental shelf off Alagoas and Sergipe States (Brazil). The plankton samples were collected by horital hauls near surface by the vessel (AKAROA. Sixty-five (65) species, one (1) variety and two (2) forms were identified, belonging to thirty (30) genera and thirteen (13) families. The most representative genera were Chaetoceros and Rhizosolenia with thirteen (13) and eleven (11) species, respectively. The most representative species were: Chaetoceros coarctatus, Chaetoceros didymus, Rhizosolenia calcar-avis, Bacteriastrum delicatulum, Bacteriastrum hyalinum, Chaetoceros lorenzianus, Hemiaulus membranaceus, Hemidiscus hardmanianus, Rhizosolenia alata f. infica e Rhizosolenia styliformis, occuringin more than 50% of the studied stations. The distribution of the species were conditionated to the oceanographie conditions of the area. The neritic species predominated upon the oceanic ones, because the small width of the Northeast brazilian shelf. Among the identified species some were new occurences to the Northeast Brazilian shelf: Asterolampra marylandica, Chaetoceros cinctus and Navicula mollis. This last one cited for the first time in Brazil.

ABSTRACT - This study aims to improve the final evaluation of sugar cane (Saccharum spp) variety trial in Pernambuco state, Brazil. It includes 24 yeild trials and 61 genotypes.

The trials were grouped according to the error variance and such way that the diference between the smallest error variance did not exceed the 1 to 4 proportion. There were two common treatments to all trials, namely variety CB45-3 and Co997. The regular treatments included 37 RB varieties and 22 introduced varieties. There were three groups of experiments for the first cutting and two groups for the second cutting. Sugar yield (TPH) and sugar cane yield (TCH), in t/ha, were evaluated. In general, the statistical analysis showed that experiments, adjusted treatments and the interaction common treatments with experiments were statistically significant.

The variety CB45-3 showed an average yield of 12,97 for TPH and of 91,46 for TCH, in the first cutting trials. The same variety had average yields of 10,97 for TPH and of 70,36 for TCH, in the second cutting trials. The variety Co997 showed an average of 14,40 for TPH and of 85,54 for TCH, in the first cutting trials. The same variety had average yield of 12,53 for TPH and of 69,23 for TCH, in the second cutting trials. This confirm the trend of Co997 to be more productive than CB45-3 as far as sugar yield is concerned and of CB45-3 to be more productive than Co997 as far as sugar cane yield is concerned. The varieties Co1007, NA56-79, RB7075 and RB70103 had higher TPH and TCH yields than both common treatments. RB7138, RB7155 and RB7194 had higher TPH yield than both common treatments. RB7019, RB71156 and RB7286 had higher TPH yield than CB45-3. The varieties FAN66-35 and RB71156 had higher TCH yield than CB45-3. There was not any other variety with higher TPH than Co997. However, the varieties RB7019, RB7194, RB71156, RB71181, RB72523 and RB732628 had higher TCH yield than the variety Co997.

The varieties CB47-355, CP51-22, CP60-1 and RB70194 were not different from the two check varieties. The varieties RB7084. RB70100, RB70101, RB70106, RB70126, RB70141, RB70289, RB71191, RB72411 and PR1Ó28 had smaller TPH and TCH yields than both check varieties.

The analysis of the data available shows that the genetic variability of sugar cane, already available in Pernambuco, would be more useful if the trials of each sugar cane microregion had the same varieties as entries. The RB vavieties 7019, 7075, 7095, 70103, 70141, 70194, 7138, 7155, 71194, 71156, 7286 and the introduced varieties Col007, NA56-79, CB47-355, CP51-22 and CP60-1 should be evaluated in more detailed experiments.

ABSTRACT - Conveniently stabilized and stored leaves of Cassia fastuosa Wild., Leguminosae collected in 1973, were subjected to extraction methods of anthracenic compounds. Three aglicon (A, B and C) were detected in the ethereous extract and A and B sennoside in the ethanolic extract. Thin layer chromatography and melting point proved that A and C aglicon were aloemodin and emodin, respectively. Ultra-violet and infra-red absorption spectra showed the B aglicon as being a rhein. The Rf values in the thin layer chromatography of ethanolic extract resembled those of standard A and B sennoside. In quantitative determinations an yield of 2,48% in rhein and 4,8% in Sennoside B was obtained. Preliminary biological assay in 10% aqueous extract confirmed the laxative activity and no toxic effect was observed.

ABSTRACT - Podocarpus lambertii Kl., the "pinheiro-bravo" follows the distribution of Araucaria angustifolia (Bert.) O. Ktze., in the State Rio Grande do Sul, Brazil, but its dispersion in larger risen to Southeastern mountains. It is a Gymnospermae native with big economics potential by its timber and fibers and by ecological forest value in the region. However, it is poorly known, there are any records about anatomy and germination of the seed.

This paper deals with the physiology of seed germination and anatomy of the seed and seedling of Podocarpus lambertii.

The storage of the seeds decrease the germ inability, but the scarification of the seed increases the germination. The seed has only one tegument showing vascular tissue and lipids are the mainly reserve in the gametophyte. The seedling shows a diarch root and in the endoderm the Caspary strips are well developed, sometimes they ramified. The cortex can show some cells with these branching Caspary strips. The cotyledons are two and they have two vascular bundles but no resin canals. The leaves show only one vascular bundle and in this case attend by one resin canal.

ABSTRACT - It was made a survey on the Diatoms of the Itiberê river estuary, that bathes Paranaguá City, in the State of Paraná, Brazil, to estimate the situation of the estuarine aquatic environments, and to study the planktonic Diatoms in those environments of that State, in order to supply elements for the knowledge of this part of the planktonic florule. The work lasted from April 1980 to June 1981, with monthly collections, one in the morning and another in the evening. The work consisted of plankton collection with its proper microplankton net, measure and establishment of some mesologic variables: temperature, pH, salinity, flow velocity, pluviosity, transparence and tides. The material was mounted on sudes and identified after fixed and partialy oxidated. We recognized 132 taxa of infra-generic level and only 12 of generic level, the total distributed into 21 families and 61 genera. From 132 especule and infra-especific taxa, 38 were new citations of the Diatoms florule of the Paraná State. The best representated families, in number of infra-generic taxa, were NAVICULACEAE and COSCINODISCACEAE and, according to the same parameter, the best representative genera were Navicula, Costino discus and Nitzschia. We observed that the mesologic conditions, separately analysed, didn't constitute themselves limitant factors to the diversity in the different collection stations. We then raised the diversity grade in the different collection months, observing that two larger periods of diversity occured, one in September and October/1980 and another in January and February/1981. At last we listed the best representative infra-generic taxa in the different collection stations and we also listed the taxa which consisted new contributions to the knowledge of the Paraná State Diatoms florule.

ABSTRACT - This study is a morfologi interpretation of Anacheilium faustum (Orchidaceae) of the Encyclia glumacea group according to DUNGS & PABST. The interpretation was made over all the organs of the plant and covering its complete biologie cycle. The methodology included three procedures: 1 - Direct observation of the plant material in the field and in laboratory; 2 - Dissections and 3 - microtechnique. During the study various problems dealing with nomenclature were raised and analysed, particularly those concerning the term: pseudobuîb. Among other conclusions of the study, a new classification of the bulb of the family Orchidaceae is proposed.

ABSTRACT - A taxonomic survey of the desmids (Zygnemaphyceae) of 3 lakes in the Parque Regional do Iguaçu, located in the city of Curitiba, Paraná State, Brazil, was carried out on the basis of analysis of 75 samples gathered monthly from 5 stations during the period of January 1982 to March 1983.

114 taxa were identified and classified into 3 genera of the Family Meso taeniae eae and 14 of the Desmidiaceae. They comprised a total of 102 species, 34 varieties which are not typical for their species, and 7 taxonomic formae which are also not typical. 109 out of the 114 taxa surveyed constitute new citations for the State of Paraná.

Cosmarium with 32 taxa, Closterium with 20, and Staurastrum with 18 were the genera best represented were: Actinotaenium, Cosmocladium, Cylindrocystis, Gonatozygon, Onychonema, Penium, and Teilingia, each with a single taxon.

The greatest number of taxa (84) was observed at station 1, the smallest (47) at station 5. 5 taxa occurred during the entire period of study, but 27 in just one month. In all months desmids occurred in variable but considerable amounts. However, the greatest number of taxa occurred in January 1982, and the smallest in July of that same year.

One species and 2 varieties of Cosmarium, and one species of Staurastrum are here suggested as new to Science.

Maximum and minimum taxonomic similarities were calculated by means of the Jaccard Index, and occurred when the florulas were compared among themselves, respectively, at the 3 stations at the largest lake of the 3, and at those of the 3 lakes individually.

All taxa were identified on the basis of their classical morphological features and, whenever possible, also by the use of population samples, on account of the relatively frequent polymorphism in the group.

For each taxon identified the following information is provided: detailed description and measurements based on material studied, list of materials examined, geographical distribution within the State of Paraná, all illustrations necessary to demonstrate the morphological variation found within the population sample, and, whenever needed, the basyonym and comments.

Taxonomical problems net with during the survey are raised as follows: 1) morphological expressions were observed in 26 taxa, but in no case with taxonomic implications; 2) cell measurements were taken, which enlarged significantly the maximum and/or minimum limits usually cited in the literature for 70 taxa, but again with no taxonomic implications; 3) overlapping of diacritic characteristics between the following taxa: Closterium ehrenbergii Men. var. ehrenbergii and Closterium ehrenbergii Men. var. immane Woole, Closterium tortum Griff, and Closterium acutum (Lyngb.) Bréb. var. variabile (Lemm.) Grieg., Closterium tumidum Johns, var. tumidum and Closterium arcuarium Hugh. var. brevius Prese; 4) taxa separated by means of characteristic whose taxonomic value is poorly defined, such as the lateral margins undulations in Pleurotaenium subalternans Borge, and the radiation in Staurastrum tetracerum (Kütz.) Ralfs var. tetracerum f. tetracerum and Staurastrum tetracerum (Kütz.) Ralfs var. tetracerum f. trígona Lund.

Gathering of samples during 15 consecutive months demonstrated non-homogeneity of the qualitative distribution of the florula along the time-scale, in such a way that isolated collections were never representative of the community.

13 artificial idented keys - one for the identification of the families, one for the genera within each of the 2 families, and 10 for the species within each genus containing more than one taxon - and 171 illustrations (one map, 8 photographs, and 14 plates of line drawings) complement the text.

ABSTRACT - Leaves of mango trees (Mangifera indica L.), avocado trees (Persea americana Mill.), guava trees (Psidium guajava L.), sapodilla trees (Manilkara sapodilla (Jacq.) Gilly) cashew trees (Anacardium occidentale L.), jack trees (Arthocarpus heterophyllus L.), soursop trees (Annona muricata L.) and Surinam cherry trees (Eugenia pitanga L.) were collected in October 1983, from orchards in the coastal humid area of Pernambuco, to study their mineral composition. Orchards which included the highest number of these species were previously selected. The collected leaves were physiologically mature, with no pathological sign and located afl around the canopies of adult trees. Each tree was considered as a replicate and each orchard had at least two and at the most six replicates. The leaves were rinsed in distilled water, oven dried, ground, digested and analysed for their N, P, K, Ca, Mg, Fe, Zn, Cu and Mn content. Soil samples (0-30cm in depth) were collected in each orchard, simultaneously with the leaf samples, for physical and chemical analysis.

In general, there were differences among orchards in the mineral composition of each species. The average N contents varied from 1,63% (mango trees) to 2,54% (soursop trees) and were higher than those reported for other places while the average K contents (0,63% in sapodilla trees to 1,41% in jack trees) and Fe contents (56 ppm in soursop trees to 96 ppm in sapodilla trees) were lower than those in other places. Cashew tree leaves in all orchards had very low Ca (0,28% and Mg (0,21%) contents while sapodilla tree leaves had low Zn content (8 ppm). The average Ca contents in other species varied from 1,10% (guava trees) to 1,70% (Surinam cherry trees), Mg contents varied from 0,33% (jack trees) to 0,52% (sapodilla trees) and Zn contents varied from 13 ppm (jack trees) to 32 ppm (Surinam cherry trees). Mn content varied from 23 ppm (Surinam cherry trees) to 175 ppm (mango trees) but variations among orchards were much greater than among species. In mango trees, Mn content varied from 28 to 810 ppm and in avocado trees from 18 to 524 ppm. The P (0,09% in sapodilla trees to 0,19% in Surinam cherry trees) and Cu contents (5 ppm in jack trees to 13 ppm in guava trees) were, in general, similar to those found in other places. The avocado plants in one place (Itapirema) were probably Mn deficient since 4 out of 6 plants had Mn contents below 11 ppm.

High leaf Mn contents were related to high soil Mn contents; there was no clear relation between leaf and soil Mg, Fe, Zn and Cu contents, while P, K and Ca contents in leaves had no relation to soil contents.

ABSTRACT - Investigations were made at Jaguaribe Beach (Itamaracá), North of Pernambuco State, from november 1981 to november 1982 concerning to the taxonomy, seasonal variation in the content of moisture, ash, protein, fat, crude fibre, mineral elements and phycocolloids of Gracilaria debilis (Forsskal) Boergesen, Gracilaria sjoestedtii Kylin, Solieria tenera (J. Agardh) Wynne and Taylor and Hypnea musciformis (Wulfen) Lamouroux. In this work were also discussed the yield and physical properties of agar-agar in two Gracilaria species and the yield of carrageenan in Solieria tenera and Hypnea musciformis. Cystocarpic plants were observed in Gracilaria debilis and G. sjoestedtii. The moisture content in the studied species varied from 62% to 84%; the ash from 6,03% to 18,75%; the protein from 3,85% to 12,67%; the fat acids from 0,40% to 1,79% and the crude fibre 0,92% to 9,51%. The highest values of Nitrogen (2,03%), Chloride (6,03%), Sulphur (4,08%), Calcium (5,20%), Copper (18,8%), Iron (6.455,8 ppm), Manganese (176,6 ppm) were detected in Solieria tenera and Phosphorus (0,29%), Iodine (0,023%), Boron 520,0 ppm), Zinc (209,8 ppm) in Hypnea musciformis. By the other hand, Magnesium (1,23%) and Sodium (1,23%) were highest in G. sjoestedtii and Potassium (1,90%) in G. debilis. The best yield of agar-agar and carrageenan were found in G. sjoestedtii (64,04%) and Hypnea musciformis (40,04%), respectively. The gel strength were highest in G. debilis and in relation to the gelation temperature and melting temperature, the majority of the samples were according to the Brazilian and American Pha macopea.

ABSTRACT - The floristic composition and structure of the tree and shrub components are analysed though a phytosociological survey. The area surveyed is covered with Araucaria forest and is located in the Estação Ecológica de Aracuri (28º13'S, 51º10'W, 900m average altitude), Esmeralda, Rio Grande do Sul. Evenly-spaced transect strips were used in sampling. Each transect strip had sampling units of two sizes superimposed on it: 160m por trees; 40m for shrubs. The phytosociological parameters of absolute and relative density, absolute and relative frequency, relative dominance and importance value index (IVI) were calculated for both sampling methods. Diversity index and stratification of individuals were also detenninated and for the commonest species DBH measurements were used to analyse the diameter classes. Sampling sufficiency was reached with 30 sampling units for the trees and 40 for the shrubs. Fifty-four species belonging to 46 genera and 28 families were found in the total survey. In the arboreal component Sebastiania klotzschiana shows the highest IVI (40.39), as well as the highest absolute density (125.0 individuals per ha), followed by Araucaria angustifolia with the second highest IVI (37.06). In the shrubby component, Brunfelsia cuneifolia and Sebastiania brasiliensis, respectively, showed highest values for all parameters used, greatly exceeding the other species. The Shannon & Wiener diversity index was estimated in 2.93 nat/individual for the arboreal component. Stratification is not very well defined but one shrubby and three discontinuos arboreal strata were detected three discontinuous arboreal strata and one shrubby stratum. Analysis of diameter classes of the most freguent species showed the expected distribution, that is, a large number of individuals in the lower classes that diminishes as diameters increase.

ABSTRACT - This paper aims to survey the planktonic Cyanophyceae (=Nostocophyceae) of the Lagoa de Tramandaí and Lagoa do Armazém in the southern State of Rio Grande do Sul, thus contributing to knowledge of Brazilian algal flora. Monthly collections were made during 24 months, from August 1976 to July 1978 in 3 different stations, 2 of them being located at the Lagoa de Tramandaí and 1 at the Lagoa do Armazém. 20 infrageneric taxa were identified corresponding to 11 genera and 4 families. Among the taxa identified, 2 were cited for the first time for Brazil and 3 for the State of the Rio Grande do Sul. For each taxon identified a detailed description is presented, which is followed by illustrations, measurements, a list of the material examined, its geographical distribution in Brazil, comments, and, when needed, the respective basionym. An artificial key was prepared for the identification of the families, genera, species varieties and forms studied.

Chroococcaceae, Merismopedia and Oscillatoria respectively were the family and the genera containing the highest numbers of taxa identified. Oscillatoria ornata Kützing ex Gomont var. ornata f. ornata was the alga present in the largest number of samples gathered. Oscillatoria limosa C. Agardh ex Gomont var. limosa f. limosa and Oscillatoria meslinii Frémy were, on the contrary, the taxa represented by the smallest number of individuals during the whole period of study. Gomphosphaeria aponina Kützing var. aponina f. aponina showed the highest frequency of occurrence among all taxa studied; it was present during 21 out of the 24 months of collection. In the samples of December 1977 and March 1978 there occurred the highest variation in the number of taxa present, 12 of them being identified in the sum of all 3 collecting stations. The highest absolute number of taxa identified occurred at station A in October 1976, December 1976, December 1977 and March 1978. There occurred a bloom of Anabaena circinalis Rabenhorst ex Bornet & Flahault var. circinalis f. circinalis at station A in October 1976, when relatively extensive greenish spots were found on the water surface. The taxonomic identification of some taxa was somewhat difficult to carry out due to the simultaneous presence of different morphological expressions of the variation range of one single taxon. Studies based on unialgal cultures of Anabaena circinalis Rabenhorst ex Bornet & Flahault var. circinalis f. circinalis and Microcystis aeruginosa Kützing var. aeruginosa f. aeruginosa were suggested since they would contribute significantly to a better delimitation of each of the two taxa.

39 illustrations distributed in 8 plates, one of them show the map with the collecting stations, and the other, the taxa identified, a table containing the data concerning the presence of all identified taxa and their respective periods of occurrence, and a remissive index of the taxa cited complement the text.

ABSTRACT - The Araucaria angustifolia is a species of great beauty and economic potential specially for the South Region of Brazil, and for this reason this species has been widely studied.

This work aims at evaluating the initial growth and development of Araucaria, as well cheeking the behaviour of the plants originated from scarified seeds and intacts cultivated in sous of fields and woods, through the analysis of the vegetative part.

In order to mount the experiment, intact and scarified seeds were used. These were cultivated during 7 months in natural environment.

The seed were planted in the last week in May. Monthly evaluations were started three months later. The following parameters were considered: fresh and dry weights of the gametophyte; fresh and dry weights of the root; root lenght; fresh and dry weights of the shoot; number of leaves; height of stem and foliar area.

After analysing the results using the different parameters above, the conclusions were the following:

1 - scarified seeds differed significanthy from intacts concerning germination and germinability rates, number of leaves, foliar area, dry weight and height of the shoot;

2 - plants originated from intacts grew larger roots and had a higher relative growth rate, a higher net assimilation rate, and heavier weight of the shoot;

3 - plants cultivaded in woods soil developed better than those cultivated in the field soil not only the plants originated from intacts, but also those originated from scarified seeds.

ABSTRACT - Preliminary phytochemical assays of aereal parts of Eupatorium littorale Cabrera revealed the presence of flavonoids. The identification was accomplished by means of analytical thin-layer chromatography (TLC) and its isolation and purification by means of preparative TLC and column chromatography. The presence of rutin in column chromatographical fractions 1.501-4.000 with eluents chloroform: methanol 1:1, was confirmed later by analytical TLC, melting point and U.V. absorption spectrometry. TLC and melting point of hidrolisated sample identified the aglicon as being a quercetin; rutin sugar components were identified as glucose and rhamnose by means of analytical TLC. The isolated flavonoid is probably the quercetin 3-rutinoside.

ABSTRACT - Taxonomic studies about the family Lauraceae Lindl. were made in the State of Pernambuco. Collects were realized in diverse areas, including all phytogeographic zones of that State, during the period from January 1982 to January 1984. Eighteen species from six genera were identified and among them Nectandra cuspidata Nees et Mart, ex Nees, N. myriantha Meissn., Ocotea laxiflora (Meissn.) Mez, O. aff. lucida (Meissn.) Vatt., O. opifera (Nees) Mart, and Persea caesia Meissn. are reported by the first time to the Northeast of Brazü and, besides, Gnnamomum chana Vatt., Ocotea brachybotrya (Meissn.) Mez, O bracteosa (Meissn.) Mez, O. duartei Vatt., O. limae Vatt. and O. pallida (Meissn.) Mez to the State of Pernambuco. The keys to the genera and species of the family were elaborated. The descriptions of the species studied as well as their illustrations and explanations about the morphology, fenology and geographic distribution are reported in this paper. The expressions hypanthium and vestigial stamens nectaries were considered as the most adapted to the morphology of the family. The genus Ocotea Aubl. was found to have the greatest representation in the State of Pernambuco. The components of the family Lauraceae were registered in the following zones: littoral zone (Cassytha filiformis L. and Ocotea gardneri (Meissn.) Mez), forest zone (Cinnamomum chana Vatt., Cryptocarya moschata Nees et Mart, ex Nees, Nectandra cuspidata Nees et Mart, ex Nees, N. myriantha Meissn., Ocotea brachybotrya (Meissn.) Mez, O. bracteosa (Meissn.) Mez, O. duckei Vatt., O. gardneri (Meissn.) Mez, O. glomerata (Nees) Mez, O. laxiflora (Meissn.) Mez, 0. limae (Vatt., O. aff. lucida (Meissn.) Vatt., 0. opifera (Nees) Mart., 0. sylvatica (Meissn.) Mez and Persea caesia Meissn.) and savannah zone (Ocotea gardneri (Meissn.) Mez). In the "Chapada do Araripe", probably in areas of "carrasco", O. duartei Vatt., O. duckei Vatt. and O. pallida (Meissn.) Mez were found. Cinnamomum chana Vatt., Oco tea duckei Vatt, O. gardneri (Meissn.) Mez and O. glomerata (Nees) Mez presented a large distribution in the State while Cryptocarya moschata Nees et Mart ex Nees, Nectandra myriantha Meissn., Ocotea duartei Vatt., O. limae Vatt and Persea caesia Meissn. presented a very restrict distribution. The following species are registered here as the first citations to others states of Brazil; Gnnamomum chana Vatt. (Ceará), Cryptocarya moschata Nees et Mart, ex Nees (Pará), Nectandra cuspidata Nees et Mart, ex Nees (Pará, Ceará, Sâo Paulo and Santa Catarina), TV. myriantha Meissn.

ABSTRACT - A phytosociological study of Atlantic hillside's "ombrofila" tropical forest (25º30'S latitude, 48º38'W longitude, 485m altitude), in the State Park Marumbi, Morretes, Paraná, south Brazil, from November 1983 till February 1985. The climate was classified as KOEPPEN'S Cfa. The samples were taken bt "point-center quater method" (COTTAM & CURTIS, 1956). Only trees with diameter equal to or greater than 4.8cm were considered. In the 80 points (each as far 10m from the next), 70 species of trees (belonging to 55 genera and 31 families) were sampled. The vegetation structure analyses was based on density, frequency, dominancy and importance value index (IVI) parameters. The most important families were Myrtaceae, Rubiaceae, Moraceae, Euphorbiaceae, Meliaceae and Nyctaginaceae. Density and frequency analysis shows some prominent species, the most important being Guapira opposita, Mollinedia sp. (2), Hieronyma alchorneoides, Bathysa meridionalis, Psychotria suturella and Alsophyla sp. Ficus organensis, Guapira opposita, Hieronyma alchorneoides, Cabralea canjerana, Mollinedia sp. (2) and Bathysa meridionalis are dominants. 28.6% of species sampled indued 75.9% of all IVI values. The forest appears to be stratified into lower, midle and upper layers. The diameters were distributed into 5cm amplitude size classes. The vegetation of the study site was compared with those of other ares in Atlantic and Aracauria forests in terms of climate, species, genera and families composition, well as the most important species and phytomass.

ABSTRACT - Taxonomical survey of the family Rhamnaceae A.L. of Jussieu in the State of Pernambuco-Brazil by morphologic analysis of the collected material during trips made between 1982-1983, from the botanical material available in the local herbarium and from other Institutes of the country. In order of identify the Species, the collected data were compared to those contained in the diagnosis or in typus, concerning dimension, shape, consistence, andpilosity of the reproductive and vegetative organs. In Pernambuco, the family is represented so far by 6 genera and 13 species: Alvimiantha tricamerata Grey-Wilson, Colubrina cordifolia* Reissek, C. glandulosa Perkins var. reitzii (M.C. Johnston) M.C Johnston, Crumenaria decumbens* Martius, Gouania blanchetiana Miquei, G lupuloides (L.) Urban, G. virgata* Reissek, Rhamnidium elaeocarpum* Reissek, R. molle* Reissek, Ziziphus cotinifoiia* Reissek, Z. joazeiro Martius, Z. platyphylla* Reissek and Z. undulata* Reissek. The 8 species marked with asterisks make up new references for Pernambuco. Colubrina rufa Reissek and Gouania polygama (Jacquin) Urban, which were already mentioned as existing in Pernambuco, had their epithets changed to Colubrina glandulosa Perkins var. reitzii (M.C. Johnston) M.C. Johnston and Gouania lupuloides (L.) Urban, respectively. The other species were only confirmed. Keys for separating genera and species, descriptions, areas of occurence, commentaries and illustration are also presented. Some species of the genera which occur in Pernambuco are also new references for other Brazilian States.

ABSTRACT - The main objective of this work is to obtain a Dentado Composto population resistant to fall armyworm (5. frugiperda) and corn earworm (H. zea), and more productive one.

It was used 363 half sib families and two checks, Dentado Composto original population and Centralmex variety.

The experiments were carried out at Vitôria de Santo Antâo and Caruaru, IPA stations (PE), during 1982/1983. Natural infestations were used an all trials and two scales note were utilized to evaluate the damage of the insects.

No pesticides were used in any experiments at all, and they were placed far from treated areas.

The 50 half sib families that presented the best performance for the three characters have concomitantly been selected and recombined at Vitoria de Santo Antao, IPA station in 1983. These families exhibited higher yields and less fall army worm damage, however there was no progress to resistance corn earworm character.

The values of heritability, genetic variation coefficient and genetic response to fall armyworm damage were 3,7%, 2,27% and 0,7% respectively. These values for corn earworm damage were 22,99%, 9,41% and 7,18%, respectively, and to yield were 12,15%, 4,74% and 2,63%, respectively.

The selected families have shown a injury of fall armyworm and corn earworm reduction of 10,3% and 0,4%, respectively, while for yield it was found an increase of 18,1%.

The selected families for recombination were not the same that have shown low damage ratios and high productions. This justifies the differences among the character averages and the genetic response mainly for H. zea damage evaluation.

ABSTRACT - A survey of the essential oil of leaves of Nectandra grandiflora Nees et Mart, ex Nees Lauraceae Lindl. was carried out. An average yield of 0.80% was obtained with extreme values of 0.70% in May 1982 and 0.93% in February of 1983 characterizing the seasonal variation.

Using techniques to evaluate the physico chemical constants of the essential oil the following results were obtained:

density, D = 0.97764; refractive index, nD 25= 1.51959; rotating power, |α| = -55.591º, and solubility -2:1, two parts of essential oil for one of 90% ethyl alcohol.

Thin layer chromatography (CCD) gave spots with RF,S characteristic of eugenol and other components.

Using gas chromatography (CG) the presence of eugenol was confirmed and α-β-γ-cariophilenes were detected, but the retention time of each one is the same and is coincident with β-terpineol, for which reason it was not possible to definitely identify the superimposed components.
