4. Chemical constituents and technological functional properties of acerola (Malpighia emarginata DC.) waste flour
Acerola is a fruit that can be consumed in the form of juice and pulp. However, during its processing, a large amount of waste is generated (seed and bagasse). Adding value to these by-products is of great interest, since their use can enrich foods with nutrients and fiber. In this study, we performed phytochemical screening, determined the proximate and min

5. Reproductive biology and early establishment of Pinus elliottii var. elliottii in Brazilian sandy coastal plain vegetation: implications for biological invasion
Pinus is the most invasive woody taxon, exceeded only by herbaceous plants. This study reports the reproductive biology and early establishment of Pinus elliottii Engelm. var. elliottii, describing its invasive properties in a protected natural area of the Brazilian coastal sandy plains. We evaluated the seed germination and rain, longevity of seed viability

6. Métodosdesuperaçãodedormênciadesementesde Flamboyant / Methods of overcoming seed dormancy flamboyant
The Flamboyant (Delonix regia (Bojer ex Hook) Raf.) is an exotic ornamental species adapted to the conditions of the Brazilian territory, belonging to subfamily Caesalpinioideae and it has seeds with hard coat that promotes seed dormancy caused by the impermeability of seed coat to water and oxygen. The aim of this study was to test different types of mechan

7. Invading potencial from Singapure almond (Terminalia catappa L.) in resting forest / Potencial invasor do chapéu-de-sol (Terminalia catappa L.) em área de restinga
Current and the next decade they will be identified in the time as group of the most excellent concerns with the ambient quality of the planet. Subjects as global heating and the eminent loss of the amount and quality of the water are argued constantly. A more specific ambient problem has worried specialists in the world all, including Brazil. One is about t

8. Research and development in the irrigated rice seeds sector in Rio Grande do Sul State / Pesquisa e desenvolvimento no setor de sementes de arroz irrigado no Rio Grande do Sul
The aim of this work was to investigate the ways in which the organizations dedicated to the research and development (R&D) of rice irrigated seeds in the Rio Grande do Sul State face the action of opportunist agents, which promote the commerce and the informal use of genetic materials protected by Law. The research problem was structured as the following qu

9. Evaluation of variety of corn in system of organic production â physiologic quality and of the storage seeds / AvaliaÃÃo de sementes de variedades de milho em sistema de produÃÃo orgÃnica â qualidade fisiolÃgica e armazenabilidade das sementes
The corn is one of the most cultivated cereals of the world, and the quality of the used seeds is important for the success of the tilling. One of the great problems of the organic agriculture is the supply of the seeds, and the improved variety becomes interesting because of being less demanding to inputs and presenting a good adaptation. The seeds of the v

10. Interactions etween ants, fruits and seeds in the cerrado : the role of ants in the biology of seeds and seedlings / Interações entre formigas, frutos e sementes em solo de cerrado : o papel de formigas na biologia de sementes e plantulas
Our knowledge about seed dispersal systems has been improved considerably in the last few years. An increasing number of studies has shown that the process of plant regeneration is often much more complex than we realize, including several different agents across subsequent steps of seed dispersal. For instance, ants may reshape the seed shadow after seeds f

11. Morphophysiological aspects development of Tabebuia serratifolia Vahl Nich. seeds / Aspectos morfofisiolÃgicos do desenvolvimento de sementes deTabebuia serratifolia Vahl nich
Tabebuia serratifolia is considered a tree symbol of Brazil, named âyellow IpÃâ and it is used in the reforestation of the degraded areas. Although due to its improper exploration it is in extinction, in spite of having protected by law for its permanent preservation in the state of Minas Gerais. The objective of this research was to evaluate the morphoph

12. A importância das palmeiras arborescentes de grande porte na dinâmica das florestas amazônicas sazonalmente secas.
We investigated and compared the determinants of palm diversity at different spatial scales: along a moisture gradient in a seasonally dry Amazonian forest and using a climatic model comprising the entire Brazilian territory. Climatic hazards seem to strongly determine the distribution of palms, with the relative importance of moisture being highly consisten
