SUMMARY:

Determining adequate procedures for conducting the germination test in forest species is important to enable the commercialization of seed lots, especially for those that are not included in the Normative Instructions. Therefore, the objective was to determine the ideal temperature and substrate conditions for the Senna siamea seed germination test, as well as to characterize the morphophysiology of the seedling establishment during the germination process and the period for seedling evaluation, in order differentiation of Senna siamea seed lots. Initially, the experiment was carried out in a 2 x 2 arrangement (substrates x temperature), using the substrates paper roll and on sand, and at 25 and 30 ° C installations. For the comparison of the seed lots, we used if the arrangement of 10 x 1 (lots x experimental condition). The percentage and speed of germination, first count, seedling length, accumulated germination, seedling morphology during germination and accelerated aging are recorded. Senna siamea seeds have a higher germinative potential in a paper roll substrate at temperatures of 25 and 30 ° C. The first germination count and a final seedling evaluation must be done at 10 and 21 days after sowing, respectively. The species has germination of epigeal type seeds and its seedlings are phanerocotyledonous. Lots being 3; 4; 6 and 9 with greater viability potential for the commercialization of seed lots and for the production of seedlings.
