Abstract:
The aim of this work was to evaluate the seeds biometry and the adequate temperature and
substratum to germination and vigor test of T. caraiba seeds. In the biometric evaluation
were estimated the length with wing, length without wing, width, thickness and weight
without wing from 30 random seeds. Were evaluate the germination percentage and the
seeding performance through the first count, average time of germination and seedling dry
weight in paper (paper roll), sand, sand + vermiculite (1:1) substrates, in three
temperatures, 25, 30 and 35 ºC, under 12 hours of photoperiod. The seedling dry weight
was evaluated only in the paper substratum. It concludes that T. caraiba seeds have, in
average, length with wing, length without wing, width, thickness and weight without wing
of 54.00, 19.88, 15.29, 2.58 mm and 0,18 g, respectively. The germination test and vigor
evaluation of T. caraiba seeds should be done in paper substratum at 30 ºC.
