Influence of mechanical scarification and single angle germination in seeds of Schizolobium parahyba

Abstract

The seeds of Guapuruvu inated tegumentary dormancy prevented the entrance of water, consequently, not occurring their germination, next to the aforementioned situation, to the work as having been listed different dormancy techniques in the formation phase of Guapuruvu in the experimental nursery of the Faculty of Social Sciences and Agrárias de Itapeva - FAIT. The new treatments were the scarification techniques for the influence of the seed sowing direction, which can be recognized as the best planting direction and the horizontal water gain as the highest emergence rates, the best treatment for T2 - mechanical scarification Opposite side of the horizontal sowing and sowing with 90% germination. The experimental work was in a completely randomized design (DIC), each day containing 15 seeds with 3 replicates each, the results were submitted to a statistical analysis by the Tukey test at 5% of the probability of error.
