1. Ecophysiology of Germination of Parkia platycephala Benth. Seeds
ABSTRACT Water is considered the most important environmental resource for the germination process. This study aimed to evaluate the germination performance of Parkia platycephala seeds under different conditions of water and saline stress. Seed germination was tested with solutions of poly (ethylene glycol) 6000 and sodium chloride (NaCl) at seven osmotic

2. Lianas of Seasonally Dry Forest: Ecophysiology and Use in Restoration Ecology / Lianas da floresta estacional semidecidual: ecofisiologia e uso em restauração ecológica
Lianas are important components of the structure and dynamics in seasonally dry forests, but there are few studies on their ecophysiology and use in restoration ecology. The objective of this study was to evaluate the ecophysiology of seeds and juveniles of species of liana in the preferences for environmental regeneration and the variables involved in using

3. Germinação de sementes e crescimento inicial de plântulas de Eschweilepia ovata (Cambess.) Miers., Trema micrantha (L.) Blume. e Ficus tomentella Miquel. / Germination of seed and early growth of seedlings of Eschweilera ovata (Cambess.) Miers., Trema micrantha (L.) Blume. and Ficus tomentella Miquel.
Several researches about germination of seeds and emergency of native species seedling have been accomplished, however, considering the great diversity of species of the Brazilian flora, the available information are still scarce. In that sense, the present study (L.) has as objective to develop protocols for the study of the germination and initial growth o

4. Germinação, emergência da plântula, produtividade e qualidade da fibra de Gossypium hirsutum L. CV. DP 660 sob ação de bioestimulante / Germination, seedling emergence, productivity and fiber quality of Gossypium hirsutum L. cv. DP 660 under action of biostimulants
Cotton is the most important vegetable fiber for man who uses it as a raw material in the production of tissues which has intrinsic qualities unequaled to in other fibers. For this reason, the viability of the seed has been receiving special attention, since its quality is demonstrated in the subsequent cultures, in terms of uniformity, greater performance o

5. Culture environment in the micropropagation of Annona glabra L. / "Ambiente de cultivo na micropropagaÃÃo de Annona glabra L."
The Annona glabra L. has aroused a great interest in Brazil in recent years, since it is a species with the capacity to adapt to several environments and it belongs to the fruit group which has medicinal properties of substances isolated from leaves, fruit and seeds. The initiatives to explore the potential of this species are incipient still, especially due

6. Relation between the size seed, the functional morphology of the cotyledons and the tolerance to different light conditions in seven tree species from tropical forest / Relação entre o tamanho da semente, a morfologia funcional dos cotiledones e a tolerancia a diferentes niveis de sombreamento em especies de florestas tropicais
Plantas de algodão (Gossypium hirsutum) dos cultivares Acala ( suscetível) e IAC-20 (tolerante) foram avaliadas quanto .ao crescimento e variações no conteúdo de açúcares solúveis, fenóis e clorofilas, e na atividade da redutase do nitrato, quando inoculadas com diferentes níveis de inoculo (0,500 e 5.000 ovos) de Meloidogyne incognita raça 3, ou
