Seed viability, germination and seedling quality patterns of three forest species for restoration in Amazonian conditions

The aim of this study was to evaluate the quality patterns Switenia macrophylla, Cedrelinga cateniformis and Ochroma pyramidale seeds seedlings in response restoration. seed viability test performed using 1 % tetrazolium (2,3,5-triphenyl chloride) during three staining times percentage vigor levels were considered according topological pattern. Germination speed, germination capacity, morphological indices plant determined aboveground belowground ratio, slenderness, degree lignification Dickson's quality. highest viable with maximum time (3 hours) verified. medium category higher species, as by a partial reddish pattern an expression their physiological quality, which reflected germination. allowed us identify species’ potential for growth development acclimatization area. correspondence analysis significant (p≤0.05), facilitated formation groups, C. found be high-enough indicator its cover restoration needs Amazonian conditions.
