    Maia, Rúbia Kécia Marins; Silva, Edivan Amaro da; Alves, Rafael Mateus; Morais, Maria Aparecida dos Santos; Vieira, Marcos Ribeiro da Silva; Silva, Luzia Ferreira da; Simões, Raquel Ferraz Jardim; Fonseca, Kelem Silva; Simões, Adriano do Nascimento

    Abstract in Portuguese:

    Resumo Etanol e ácido cítrico podem aumentar a longevidade em algumas flores de corte. Porém, seu uso deve ser de extremo cuidado, com métodos de aplicação e concentrações específicas para cada tipo de flor de corte. Assim, o objetivo foi estudar as mudanças físico-químicas e fisiológicas na longevidade de gérberas de corte cv. Mistique, submetidas a etanol (Et) e/ou ácido cítrico (AC). As hastes foram selecionadas e padronizadas a 35 cm de comprimento, mantidas a 20 ± 2 °C e UR 65 ± 2%, sob iluminação contínua. As gérberas foram submetidas a dois métodos de aplicação (pulsing 48 horas e manutenção), sob diferentes concentrações de Et (4%, 6% e 8%) e/ou AC (100 e 200 mg L-1) e água destilada (controle), a cada dois dias foi realizada análise visual, longevidade, tombamento das hastes, massa fresca, conteúdo relativo de água, extravasamento de eletrólitos e atividades das enzimas peroxidase e polifenoloxidase. Observou-se que a solução de Et (4%) + AC (100 mg L-1), proporcionou maior longevidade, independente do método de aplicação. Estes resultados foram base para um terceiro experimento, no qual as hastes foram imersas por pulsing, em soluções de Et (4%) e/ou AC (100 mg L-1), água destilada (controle). Foi verificado que as gérberas submetidas à solução com Et + AC, apresentaram menor perda de massa fresca, maior conteúdo relativo de água, menor extravasamento de eletrólitos e aumento mais lento nas atividades da polifenoloxidase e peroxidase. Isto proporcionou retardo no tombamento das hastes e melhor aparência, resultando em maior longevidade, quando comparada as demais soluções.

    Abstract in English:

    Abstract Ethanol and citric acid can increase longevity in some cut flowers. However, its use must be extremely careful, with application methods and specific concentrations for each type of cut flower. Thus, the objective was to examine the physico-chemical and physiological changes in Gerbera cv. Mistique cut flowers treated with ethanol (Et) and/or citric acid (CA). Stem were selected and standardized to a length of 35 cm and maintained at 20 ± 2 °C and RH 65 ± 2%, under continuous lighting. The flowers were subjected to two application methods (pulsing for 48 h and maintenance), using different concentrations of Et (4%, 6%, and 8%) and/or CA (100 and 200 mg L-1) and distilled water (control). A visual assessment and analyses of longevity, stem bending, fresh mass, relative water content, electrolyte leakage, and peroxidase and polyphenol oxidase enzyme activities were performed at every two days. The Et (4%) + CA (100 mg L-1) solution provided the greatest longevity, regardless of the application method. These results were the basis for a third experiment, in which the stems were immersed in pulsing solutions of Et (4%) and/or CA (100 mg L-1) and distilled water (control). The Gerbera flowers under Et + CA solution showed lower fresh mass loss and electrolyte leakage, higher relative water content and a slower increase in polyphenol oxidase and peroxidase activities. This allowed for delayed stem bending and better appearance, resulting in greater longevity compared to the other solutions.

    Santos, Patrick Luan Ferreira dos; Castilho, Regina Maria Monteiro de; Pinheiro, Raquel Reia

    Abstract in Portuguese:

    Resumo Caesalpinia pulcherrima apresenta diversos usos no mundo, mas há grande disparidade de germinação no momento da produção de mudas, sendo esse fator talvez atribuído à posição que a semente ocupa no fruto. Assim, o objetivo deste trabalho foi avaliar aspectos germinativos e concentrações de proteínas de reserva em sementes de C. pulcherrima em função de sua posição no fruto. O trabalho foi conduzido em casa de vegetação, em delineamento inteiramente casualizado, com cinco tratamentos de posição da semente na vagem, com base na distância da semente ao pedúnculo (P1-distal, P2-distal/mediana, P3-mediana, P4-proximal/mediana, P5-proximal). Sendo oito repetições, com oito sementes por repetição, que foram colocados para germinar durante 21 dias em bandejas de poliestireno expandido cheios de substrato. Foram avaliados a porcentagem, índice de velocidade e tempo médio de germinação e germinação de 50% da população. Ainda em laboratório, foi determinado o conteúdo das proteínas de reserva (albumina, globulina, prolamina e glutelina). Os resultados foram submetidos à análise de variância e teste de tukey e determinado o coeficiente de correlação. Houve influência da posição da semente sobre o fruto na germinação e nas proteínas de reserva de C. pulcherrima, onde a posição proximal/mediana apresentou excelentes resultados, tendo correlações das frações albumina, globulina e glutelina com alguns parâmetros germinativos, sendo então o uso de sementes da posição proximal/mediana é recomendado para a propagação da espécie.

    Abstract in English:

    Abstract Caesalpinia pulcherrima has diverse uses in the world, including ornamental and landscape characteristics, but there is a great disparity of germination during the time of seedlings production, being this factor attributed to the position of the seeds in fruits. This study aimed to evaluate some germinative aspects and concentration of reserve proteins in C. pulcherrima seeds in the function of its position in fruits. The work was carried out in greenhouse, in a completely random experimental design, with five seed position in the pod, based on the distance from seed to the peduncle (P1 - distal, P2 - distal/median, P3 - median, P4 -proximal/median, P5 - proximal). Eight replicates with eight seeds each, were sowed to germinate for 21 days in expanded polystyrene trays filled with substrate. The percentage, speed index, average germination time and 50% germination time of the plantlets were evaluated. The reserve proteins (albumin, globulin, prolamin and glutelin) contents were also determined. There was influence of the position of the seed in the fruit on germination and reserve proteins contents. The proximal/median position showed excellent results, having correlations of albumin, globulin and glutelin concentrations with some germinative parameters. Therefore, the use of proximal/median position of the seeds is recommended for C. pulcherrima propagation.

  • Study of natural ventilation in a Gothic multi-tunnel greenhouse designed to produce rose (Rosa spp.) in the high-Andean tropic Scientific Article

    Munar, Edwin Andres Villagran; Aldana, Carlos Ricardo Bojacá

    Abstract in Portuguese:

    Resumo Nas regiões tropicais, a produção de plantas ornamentais é desenvolvida exclusivamente em estufas plásticas ventiladas de forma natural, o que significa que em algumas ocasiões microclimas inadequados são gerados com altas temperaturas e umidade que limitam o desenvolvimento produtivo das plantas. O objetivo deste trabalho foi estudar os fluxos de ar, a distribuição de temperatura e umidade relativa do ar dentro de uma estufa alternativa projetada para a produção de rosa (Rosa spp.). Três configurações de ventilação, ventilação lateral (SV), ventilação de telhado (RC) e telhado combinado e ventilação lateral (RSV) foram analisadas. O desenvolvimento metodológico baseou-se na utilização de um modelo de simulação numérica CFD-2D previamente validado, que mostrou um ajuste adequado entre os dados medidos e simulados, obtenção de valores de MAE e RMSE para temperatura e umidade relativa de 0,44 e 0,47 ° C, 3,99 e 4,04% respectivamente. Os resultados obtidos para as condições climáticas predominantes da região de estudo mostraram que as maiores taxas de ventilação foram obtidas para o RSV, com valores de 0,044 e 0,182 m3m-2s-1, essa eficiência de ventilação propiciou a geração de um microclima homogêneo, com valores de temperatura e umidade relativa adequados para a produção de rosa (Rosa spp.).

    Abstract in English:

    Abstract In tropical regions the production of ornamentals is developed exclusively in naturally ventilated plastic greenhouses, which sometimes leads to inappropriate microclimates with high temperatures and humidity that limit the productive development of plants. The aim of this work was to study air flows, temperature distribution and relative humidity inside an alternative greenhouse designed to produce rose (Rosa spp.). Three configurations of ventilation, side ventilation (SV), roof ventilation (RC) and combined roof and side ventilation (RSV) were analyzed. The methodological development was based on the use of a previously validated CFD-2D numerical simulation model, which showed an adequate fit between the measured and simulated data, obtaining MAE and RMSE values for temperature and relative humidity of 0.44 and 0.47 °C, 3.99% and 4.04% respectively. The results obtained for the predominant climatic conditions of the study region showed that the highest ventilation rates were obtained for RSV, with values of 0.044 and 0.182 m3m-2s-1, this ventilation efficiency propitiated the generation of a homogeneous microclimate, with temperature and relative humidity values adequate to produce rose (Rosa spp).
  • Optimal planting density for cut Lilium and tuberose production Scientific Article

    Ahmad, Iftikhar; Naeem, Waqas Hussain; Abdullah, Bilal

    Abstract in English:

    Abstract Lilium and tuberose are promising geophytic flowers, which have high market demand in global floral markets. A study was conducted to optimize planting densities for cut lilium and tuberose production. Bulbs of Asiatic lily ‘Brunello’ and tuberose ‘Single’ were planted on 7.5 cm, 15.0 cm and 22.5 cm between bulbs while ridge were spaced at 60 cm apart. Lilium bulbs planted at 22.5 cm took 185 d, while tuberose took 101 d to produce flowers as compared to 7.5 cm spacing (173 d and 93 d, respectively). Bulbs of lilium and tuberose planted at 22.5 cm resulted in tallest plants with highest leaf area for both tested species, 69.1 cm and 11.4 cm2 for lilium and 110.6 cm and 30.2 cm2 for tuberose, respectively. Both species had highest number of florets with longer stem/spike length and stem/spike diameter when planted 22.5 cm apart, while close planting further decrease number of buds/florets and stem/spike length. Similar results were recorded for fresh weight of a stem, while vase life and dry weight of a stem were relatively less affected by plant spacing. However, lilium and tuberose bulbs when planted at 22.5 cm plant spacing produced higher number of best quality stems for market as compared to other planting densities.
  • Harvest stages and pulsing in ornamental sunflower ‘Sunbright Supreme’ Scientific Article

    Nascimento, Ângela Maria Pereira do; Paiva, Patrícia Duarte de Oliveira; Manfredini, Guilherme Mariano; Sales, Thaís Silva

    Abstract in Portuguese:

    Resumo A utilização do girassol ornamental como flor de corte vem crescendo devido ao surgimento de novas cultivares e a demanda do mercado de floricultura por novos produtos, no entanto, são escassos os trabalhos relacionados à pós-colheita dessa espécie. Assim, objetivou-se avaliar as relações hídricas e durabilidade de inflorescências da cultivar Sunflower ‘Sunbright Supreme’ coletadas em três diferentes pontos de colheita e submetidas ou não ao pulsing de sacarose. As hastes florais foram coletadas com as inflorescências totalmente abertas, em um estágio intermediário de abertura ou fechadas e, em seguida, foram padronizadas em 50 cm e mantidas armazenadas em água ou em solução de 4% de sacarose durante 24 horas. Após esse período, as hastes foram dispostas em frascos vedados contendo 500 mL de água. A cada três dias, as hastes foram avaliadas quanto a massa fresca, volume de solução consumida, abertura floral, durabilidade total e qualidade visual considerando-se uma escala de notas que considera padrões de coloração, turgescência e curvatura do pedúnculo. Os cálculos das taxas de absorção e transpiração foram realizados considerando-se os valores de massa fresca e variação no volume de água consumido. Foi observado aumento na absorção de água e ganho de massa fresca pelas inflorescências até aproximadamente o sétimo dia de avaliação sendo que, após esse período, houve redução de massa e aumento nas taxas de transpiração. Hastes coletadas fechadas, fechadas com pulsing e no estágio intermediário com pulsing mantiveram-se na qualidade comercial cerca de quatro dias a mais que as colhidas abertas (com e sem pulsing) e em estádio intermediárias, sem a realização de pulsing. O pulsing de sacarose favorece a abertura floral de hastes coletadas em todos os estágios de colheita. O balanço hídrico positivo foi observado até o sétimo dia de avaliação e contribui para a manutenção da qualidade comercial de girassol ornamental. Recomenda-se a colheita precoce de inflorescências de girassol ornamental ‘Sunbright Supreme’ e aplicação de pulsing de sacarose a 4%.

    Abstract in English:

    Abstract The use of ornamental sunflower as a cut flower has been increasing due to the advent of new cultivars and the demand of the flower-growing market for new products. However, there are few studies related to postharvest of this species. The objective of this research was to evaluate the water balance and durability of ‘Sunbright Supreme’ sunflower collected at three different harvest stages and submitted or not to a pulsing with sucrose. The flower stalks were collected fully open, at an intermediate opening stage and also closed; they were then standardized at 50 cm and stored in water or 4% sucrose solution during 24 hours. After this period, stalks were maintained in sealed bottles containing 500 mL of water. Fresh matter, water consumption, flower opening, complete durability and visual quality of stems were evaluated every three days, considering a rating scale of color, turgescence and stalk bending. Rates of absorption and transpiration were calculated considering the fresh matter and variation in water volume. There was an increase in fresh matter and high water consumption in inflorescences until the seventh day; after this period, there was a reduction in weight and increased transpiration rates. Stems collected closed, closed with pulsing and at an intermediate stage treated with pulsing were maintained in commercial quality about four days longer than the open harvested (with and without pulsing) and intermediate without pulsing. Sucrose pulsing leads to flower opening of stalks collected at all harvest stages. The positive water balance was observed until the seventh day and contributes to the maintenance of commercial quality in ornamental sunflower. The early harvest of ornamental sunflower ‘Sunbright Supreme’ is recommended, besides the application of 4% sucrose pulsing.
  • Pollen viability and stigma receptivity in Swainsona formosa (G.Don) J.Thompson (Fabaceae), an ornamental legume native to Australia Scientific Article

    Zulkarnain, Zulkarnain; Eliyanti, Eliyanti; Swari, Elly Indra

    Abstract in English:

    Abstract Pollen viability and stigma receptivity are prerequisites for successful cross-pollination and seed set in Swainsona formosa. In this study, the pollen viabilities and stigma receptivities was assayed by in vitro pollen germination and simple hand-pollination method on glasshouse-grown plants, respectively. The viability of pollen grains was tested under three different storage conditions: 1) pollen grains were left on the plant in the glasshouse under natural conditions, 2) pollen grains were harvested and kept at a low temperature (4 °C) in total darkness, and 3) pollen grains were kept in a dry freezer (−10 °C) and in total darkness. Meanwhile, stigma receptivity was determined by hand-pollination using fresh pollen grains on flower of glasshouse-grown plants at one day before anther dehiscence up to 8 days after anther dehiscence. The results showed that pollen grains could be stored at 4 °C for up to 28 days without significantly losing their viability. Pollen longevity could be extended beyond two months when stored at −10 °C and under dry conditions. These findings provided a simple and economically sound method for storage of S. formosa pollen. In addition, stigma receptivity was found to be receptive from one day before anther dehiscence and reached its peak within four days after anther dehiscence. These results provide a valuable background to the conventional breeding of this species to create hybrids through cross-pollination.
  • Luminosity levels and substrates composition on Bermuda Grass development Scientific Article

    Amaral, João André do; Pagliarini, Maximiliano Kawahata; Haga, Kuniko Iwamoto; Castilho, Regina Maria Monteiro de

    Abstract in Portuguese:

    Resumo Gramado é parte fundamental na composição de campos esportivos. Alguns aspectos devem ser levados em consideração no processo de escolha da espécie a ser utilizada, como a utilização do gramado (tolerância ao pisoteio), manejo do gramado, condições físico-químicas do solo e tolerância ao sombreamento. Com a realização de eventos esportivos no Brasil, houve a necessidade de reformas e modernizações das arenas de futebol. Dentre as alterações na arquitetura está a implantação de coberturas nos estádios, o que resultou em uma redução da luminosidade, afetando o desenvolvimento normal do gramado. Objetivou-se com o experimento avaliar a influência da luminosidade e de substratos no desenvolvimento de grama bermuda (Cynodon dactylon x C. transvaalensis). Foi conduzido em esquema fatorial 5 x 4 (substratos x luminosidades), em delineamento inteiramente casualizado com 20 tratamentos e 3 repetições. Os substratos foram: S1 = Solo, S2=Solo+areia(2:1), S3=Solo+matéria orgânica(1:1), S4=Solo+matéria orgânica+areia(2:1:1) e S5=Matéria orgânica+areia(3:1), em quatro condições de luminosidade: pleno sol, 30%, 50% e 80% de sombreamento, durante seis meses. Foram avaliados: composição da fertilidade dos substratos, radiação solar, altura de grama a massa fresca e massa seca. O sombreamento interferiu no pleno desempenho da grama bermuda, sendo que esta tolera sombreamento intermediário (30% e 50%). Substratos que continham maiores teores de matéria orgânica submetidos ao sombreamento tiveram o desempenho prejudicado.

    Abstract in English:

    Abstract Turfgrass is a fundamental part in sports fields' composition. Some aspects should be taken into account in the choosing species process, such as turfgrass use (trampling tolerance), turfgrass management, physical-chemical soil conditions and shade tolerance. With accomplishment of sporting events in Brazil, there was requirement for football arenas reform and modernization. Among architecture alterations, coverings implantation was noticed, resulting luminosity reduction affecting turfgrass development. Therefore, the objective of this work was to evaluate the influence of luminosity and substrates on Bermuda grass (Cynodon dactylon x C. transvaalensis) development. The experiment was conducted in a 5 x 4 factorial scheme (substrates x luminosities), in completely randomized design with 20 treatments and 3 replicates. The substrates were: S1 = Soil, S2=Soil+sand(2:1), S3=Soil+organic matter(1:1), S4=Soil+organic matter+sand(2:1:1) and S5=organic matter+sand(3:1), in four luminosity conditions: full sun, 30%, 50% and 80% of shading for six months. We evaluated substrates fertility composition, solar radiation, grass height and fresh and dry mass. Shading interfered on Bermuda grass development, which tolerates intermediate shading (30% and 50%). Substrates containing the highest levels of organic matter submitted to shading had impaired turfgrass performance.
  • Efficacy of vermicompost and/or plant growth promoting bacteria on the plant growth and development in gladiolus Scientific Article

    Karagöz, Fazilet Parlakova; Dursun, Atilla; Tekiner, Nasibe; Kul, Raziye; Kotan, Recep

    Abstract in English:

    Abstract The use of environmental and sustainable ornamental flower production practices with renewable resources has drawn worldwide interest. One of these renewable resources is vermicompost (earthworm castings). In recent years, increasing demand for improving environmental quality have focused on the importance of Plant Growth Promotion Bacteria (PGPBs) in agriculture. Vermicomposts also help microbial agents function effectively in soil. In this study, a total of six treatments [A: PGPB formulation, B: Not autoclaved vermicompost, C: Autoclaved vermicompost, D: Not autoclaved vermicompost+PGPBs, E: Autoclaved vermicompost+PGPBs, F: Control (untreated bacteria and vermicompost)] were tested for their effects on the plant growth and development parameters in gladiolus (Gladiolus grandiflorus L. ‘Red Beauty’) in greenhouse condition. Vermicompost was added to the related pots by dissolving in water. After the addition of vermicompost, PGPB formulation was given immediately to related pots. All the treatments were applied to soil once in three leaf stage, close to the plant root zone. Parameters in terms of yield and quality attributes of plant and corm were determined and analyzed. The treatment A increased in plant height of gladiolus of 24.55% rate. The earliest times to flowering was determined in E application (100.48 day), which also increased in corm diameter with rate of 17.41% and number of corms and cormels with rate of 151.83% according to F application. Results indicated that the treatment E promoted overall better performance as compared to other treatments diameter of flowers for number of leaves per plant, number of florets per spike, stem diameter, spike length, fresh and dry weight of flowers, the number and diameter of corm. Autoclaved vermicompost can be good choice in gladiolus cultivation but it should be enriched with PGPB.

    Abstract in Portuguese:

    Resumo O cultivo de flores é uma alternativa de diversificação de produção e renda para as propriedades familiares, sendo o gladíolo uma opção de flor de corte. O objetivo deste trabalho foi divulgar a cultura do gladíolo como alternativa de diversificação e renda para pequenos produtores rurais através de um projeto de extensão onde foram demonstradas as técnicas de manejo da cultura durante o seu ciclo de desenvolvimento. Para isso, foi firmada uma parceria com a instituição de extensão rural EMATER/RS-ASCAR, com o intuito de identificar produtores interessados em cultivar o gladíolo em suas propriedades. O projeto de extensão foi desenvolvido em cinco municípios da região da Depressão Central do Rio Grande do Sul. Juntamente com os extensionistas da EMATER/RS-ASCAR, foi acompanhado o ciclo de desenvolvimento do gladíolo, indicando aos produtores as principais técnicas de manejo do plantio à colheita. Ao todo, foram produzidas aproximadamente 2400 hastes de gladíolo, que foram comercializadas em feiras locais no Dia das Mães. Em todos os locais houve grande procura e consumo das hastes florais, demostrando aceitação do consumidor por hastes de gladíolo para o Dia das Mães. Esta atividade demostrou ser rentável aos produtores familiares. Este sistema de produção incentiva a produção em cadeias curtas, contribui para o crescimento da produção local de flores e pode contribuir para diminuir o êxodo rural e a sustentabilidade das futuras gerações no campo.

    Abstract in English:

    Abstract Flower crops are an alternative for diversification in small farms, being gladiolus an option of cut flower. The objective of this study was to disseminate the gladiolus crop as an alternative for diversification and profit for small farms through an extension project where crop management practices were demonstrated during its development cycle. An extension project was carried out in partnership with a rural extension agency, EMATER/RS-ASCAR, to identify the farmers interested in diversifying their production system for growing gladiolus. The extension project was developed in four counties in the Central region of the Rio Grande do Sul/Brazil. Together with the extensionists of EMATER/RS-ASCAR, farmers were assisted during the entire production cycle and learned the management practices from planting to harvesting. Altogether, approximately 2,400 gladiolus spikes were produced, which were marketed one week before and during Mother's Day week at local fairs. In all the counties, the demand and consumption of the flower stems were high, demonstrating acceptance of the consumers of gladiolus stems on Mother's Day. The gladiolus production has proven to be profitable for small family properties. This system encourages the production in short-chains, contributes to the growth of local flower production and may contribute for decreasing rural exodus and sustainability for future generations.
