Abstract The objective of this study was to correlate the gender and behavior of consumers of organic foods enriched with functional properties. The study was carried out by investigating the profile of organic and functional food consumers through the application of a questionnaire. A total of 1230 responses (of the questionnaire) were collected from people from all Brazilian states through social networks and e-mails following the snowball technique during the months of February and March 2017. The results showed that women expressed greater interest in consuming organic foods enriched with functional properties compared to men. Men and women agree that organic food are produced in a sustainable. Their high price, difficult access, irregular supply and availability in few establishments were highlighted as the main limiting factors for not consuming organic food, while an increased motivation (of consumption) was related to the awareness that organic foods are healthier and can improve quality of life. Fruits and vegetables are the most consumed organic foods among men and women, however women consume more functional foods than men. Thus, there are few differences in behavior and eating habits of organic foods between men and women.

Besouros do gênero Rhinochenus sp. (Coleoptera: Curculionidae) danificam sementes de espécies da flora do Cerrado brasileiro como o jatobá (Hymenea courbaril L.) e a copaíba (Copaifera langsdorffii Desf.). Este trabalho teve como objetivo avaliar a morfometria de pupas e adultos de R. stigma, bem como aspectos comportamentais, como a emissão de sons, para auxiliar a sexagem desta espécie. Os insetos foram obtidos de frutos de jatobá coletados no Município de São Gonçalo do Rio Preto, em Minas Gerais, Brasil. As características morfométricas de pupas e adultos não apresentaram diferenças pelo teste t, não sendo seguras para a diferenciação dos sexos. Para adultos de R. stigma, a sexagem só foi possível após a morte, pela dissecação dos órgãos genitais.

Beetles of genus Rhinochenus sp. (Coleoptera: Curculionidae) damage the seeds of species of flora of Brazilian savannah such as jatobá (Hymenea courbaril L.) and copaiba (Copaifera langsdorffii Desf.). Thus, the objective of the present was to evaluate the morphology of pupae and adult R. stigma, as well as behavioral aspects such as emission of sounds, to assist in sexing this species. The insects were obtained from jatobá fruits collected in São Gonçalo do Rio Preto, Minas Gerais State, Brazil. The morphometric characteristics of both phases did not differ by t test, being not safe for the differentiation of the sexes. For adults of R. stigma, sexing was possible only after death, by dissection of the genitalia.

Com a crescente demanda por produtos florestais, torna-se necessário ampliar o conhecimento sobre as espécies de maior importância econômica, especialmente no que se refere ao armazenamento de sementes. Entre os métodos de conservação existentes a crioconservação se apresenta como um dos mais baratos e eficientes. Neste trabalho, objetivou-se testar o comportamento fisiológico das sementes de Pinus elliottii Engelm. submetidas ao armazenamento em nitrogênio líquido; ambiente de laboratório e geladeira. O experimento foi conduzido no Laboratório de sementes da Universidade Federal dos Vales do Jequitinhonha e Mucuri, em Diamantina, Minas Gerais. As sementes foram adquiridas em junho de 2007, por doação da empresa Rigesa Ltda. Para a realização deste trabalho foram testados três tipos de armazenamento: 1) nitrogênio líquido à temperatura de -196º C; 2) ambiente de laboratório; 3) geladeira. Todos os tratamentos acima foram avaliados após um período de 0, 40, 80 e 120 dias de armazenamento. Os testes de vigor e germinação e velocidade de germinação foram montados em gerbox, com papel germitest e umedecidos com água destilada e mantidos em germinador BOD à 25º C. Também foram avaliadas as características comprimento de plântulas, massa verde e massa seca das plântulas. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5% de significância. Constatou-se que houve perda da qualidade fisiológica das sementes de P. elliottii em todos os tratamentos. A crioconservação de sementes de P. elliotti pode ser utilizada como alternativa de armazenamento nos bancos de germoplasma.

Due to the growing demand for forest products, it is necessary to increase knowledge about the tree species of economic importance, especially in relation to seed storage. One method to study forest species is the storage of seeds. Cryopreservation is the cheapest and the most efficient method of seed preservation. The objective of this study was to test the behavior of Pinus elliottii Engelm. seeds storaged on liquid nitrogen; laboratory environment and refrigerator. The experiment was conducted in the seed Laboratory of the Federal University of the Jequitinhonha and Mucuri Valley. The seeds were donated by Rigesa Ltda on June 2007. Three types of storage were tested: 1) liquid nitrogen temperature of -196 º C, 2) laboratory environment, 3) refrigerator. All treatments were evaluated at 0, 40, 80 and 120 days of storage. The vigor, germination and germination rate tests were mounted on gerbox with blotters and moistened with distilled water and kept in BOD incubator chamber at 25 º C. Seeds length, green mass and dry mass were also evaluated. The data were subjected to analysis of variance and means compared by Tukey test at 5% significance level. It was found that there was loss of quality of the Pinus elliottii seeds in all treatments. Cryopreservation of P. elliotii seeds can be used as an alternative of storage in genebanks

ABSTRACT The aim of this study was to quantify the damage caused by Caryedes sp. in seeds of E. contortisiliquum; to test different methods to overcome dormancy; and to determine the influence of this damage on the germination and vigor of the seeds. Healthy seeds were submitted to five treatments in order to overcome dormancy. Five-hundred fruits with a total 5,245 seeds, with a mean of 10.47 ± 2.99 per fruit, were evaluated. As a result, 9.00 ± 3.32 were considered healthy and 0.26 ± 0.63 were damaged by the bruchid. The scarification toward the heel promoted higher germination and it was used for comparison to the attacked seeds. The bruchid attack can significantly reduce the germination of tamboril seeds.

RESUMO O objetivo deste trabalho foi quantificar o dano de Caryedes sp. em sementes de Enterolobium contortisiliquum; testar diferentes metodologias de superação da dormência; e determinar a influência destes danos na germinação e vigor. As sementes sadias foram submetidas a cinco tratamentos para superação de dormência. Foram avaliados 500 frutos totalizando 5245 sementes, com média de 10,47 ± 2,99 por fruto. Destas, 9,00 ± 3,32 estavam sadias e 0,26 ± 0,63 danificadas pelo bruquídeo. A escarificação mecânica no sentido do hilo promoveu maior germinação e foi utilizada para comparar com as sementes atacadas. O ataque do bruquídeo pode diminuir significativamente a germinação das sementes de tamboril.
