Seeds germination stability varies on environmental and genetical, and constitutes an important factor for agriculture and forest development.

The work presents as scientifically novel the seed germination ecophysiological study and the economically interesting species establishment and the tropical humid forests, taking into account morphonutritional and physiological pattern ; it describes dominance and dispersion mechanisms,  and seeds´ longevity and vigour under abiotic stress conditions. It is proposed a methodology for the identification of early pioneer and late forest plants groups´ ecological functions, based on seminal patterns, which has been successfully applied in seeds of 78 agriculturally interest species (24 vegetables y 4 fruit producing ones), forage leguminous (17), aromatic plants (8)and from natural ecosystems (22 forest ecosystems and 3 coastal ones)

The knowledge about dominance types, besides its scientific value, contributes to the comprehension of tropical forests regeneration process. It is recommended the application of hydric treatments combined with termical chock treatments on arboreous and vegetables species seeds, totally novel for the elimination of seminal dominance, germination increase , plants establishment and production (yields) through low consumables procedures..

From the results , there are 5 of them constituting new reports at world scale, 4 of which were registered (CENDA) and have been awarded. Research have brought about 39 publications, from which 22 articles have been published in prestigious journals (ex. Seed Science and Technology, Ecotrópicos), as well as 7 thesis. A total of 34 works have been presented in scientific events, 6 of them of international character.
