1. Morphological aspects and embryonic development after the dispersion of pirenes of Ilex paraguariensis A. St. Hil
ABSTRACT The objective of this work was to identify and describe the morphological aspects of the pyrene and the different stages of developing embryos of Ilex paraguariensis. The pyrenes were collected in the year 2016 and 2017, of ripe fruits. The pyrenes, a total of 400 per site and year of collection, remained for 24 h immersed in water for the section a

2. Nutritional, physicochemical and anatomical evaluation of creole corn varieties from the region of the Costa Chica of Guerrero
Abstract Corn (Zea mays) is the most consumed cereal in México, so it is necessary to know the nutritional and anatomical quality of the grains, which have been the main conservation and consumption criteria of the prehispanic peoples. This practice has allowed to preserve varieties of Creole corn, however, due to the lack of knowledge of these characterist

3. SORPTION ISOTHERMS AND ISOSTERIC HEAT OF PERICARP AND ENDOSPERM TISSUES OF ARABICA COFFEE FRUIT
ABSTRACT The aim of this study was to evaluate and model the hygroscopic equilibrium and isosteric heat curves of pericarp and endosperm tissues of arabica (Coffea arabica) coffee fruit, in different temperature and relative humidity conditions. Sorption isotherms were drawn under temperatures from 20°C to 70°C and relative humidity ranging between 10% and

4. Seed reserves reduction rate and reserves mobilization to the seedling explain the vigour of maize seeds
Resumo: Compreender como a dinâmica de reserva ocorre durante a germinação e formação de plântulas é determinante para avanços na tecnologia de sementes. Objetivou-se com este trabalho verificar qual temperatura de envelhecimento acelerado é mais eficaz para separar níveis de vigor de sementes de milho e avaliar a dinâmica de reservas durante o pr

5. Influência da qualidade micotoxicológica e nutricional de híbridos de milho no custo da ração de frangos de corte
RESUMO Objetivou-se avaliar as variáveis micotoxicológicas e nutricionais de híbridos de milho com diferentes características que influenciam no custo da ração para frangos de corte. Foram avaliados 26 híbridos de milho geneticamente modificados nas safrinhas de 2016 e 2017, com diferentes germoplasmas, textura de endosperma e duração do ciclo. Nos

6. Post pollination events in a self-sterile hexaploid monoembryonic lineage of Handroanthus serratifolius (Vahl) S. Grose (Bignoniaceae)
ABSTRACT In diploid late-acting self-incompatible (LSI) species of Bignoniaceae, self-pollinated pistils show a marked delay in ovule penetration by pollen tubes, followed by delayed, but otherwise normal, initial stages of endosperm development and subsequent pistil abscission. Most polyploid species of Bignoniaceae are apomictic and set selfed fruits with

7. A survey of whole-plant corn silages from Minas Gerais dairy farms
ABSTRACT Whole-plant corn silage (WPCS) is a commonly used forage for feeding dairy cattle in Brazil. The aim of this study was to evaluate on-farm ensilaging practices and the nutritional value, microbiology and fermentation profiles of WPCS from dairy farms in the south of the state of Minas Gerais, Brazil. Silages from 54 dairy farms located in nine cit

8. A new, harmless, high-throughput endosperm-based DNA extraction method for wheat
RESUMO: Neste estudo, foi desenvolvido um método de extração de DNA não destrutivo, de alto débito e endosperma. Para verificar a natureza não destrutiva deste método, um teste de germinação foi realizado em 288 sementes após a amostragem do endosperma, o que deu uma taxa de emergência de plântulas maior (97,6%) do que a do grupo controle (92%).

9. Gene expression during the germination of coffee seed
Resumo: A germinação da semente do café (Coffea arabica L.) é resultado de eventos que ocorrem simultaneamente no embrião e endosperma. Para entender os mecanismos moleculares responsáveis por estes eventos, nós realizamos uma análise transcricional do embrião e dos endospermas micropilar e lateral de sementes embebidas por 10 dias. O sequenciamento

10. Tomato seed image analysis during the maturation
Resumo: O potencial fisiológico das sementes está diretamente relacionado à normalidade do processo de formação delas, sob ponto de vista morfológico, estrutural e funcional. Deste modo, o objetivo deste trabalho foi avaliar a morfologia interna de sementes de tomate, híbrido BRS Nagai, em diferentes estádios de maturação, por meio da análise de i

11. Diversity between Jatropha curcas L. accessions based on oil traits and X-ray digital images analysis from it seeds
Abstract Jatropha curcas L. is a species with high potential for the biodiesel production. Therefore, the oil yield and quality from it seeds should be known. This study aimed to estimate the correlation between morphological traits, yield and oil quality evaluated in the seeds, to know the genetic diversity between J. curcas accessions and it behavior regar

12. Enzyme activity and reserve mobilization during Macaw palm ( Acrocomia aculeata ) seed germination
ABSTRACT Reserve mobilization in seeds occurs after visible germination, which is marked by the protrusion of the radicle or cotyledonary petiole, as in species of Arecaceae. Acrocomia aculeata (macaw palm), usually produces hard seeds whose endosperm has mannan-rich cell walls. We investigated the composition of storage compounds in macaw palm seed and the
