Abstract

Leucaena leucocephala seedlings production is limited by seed dormancy. In the present study we tested different dormancy breaking methods in leucaena seeds, through a completely randomized design experiment with six treatments and four repetitions. The treatments were composed by T0-Control, T1- immersion in cold water for 24 hours, T2- immersion in cold water for 48 hours, T3- immersion in sulfuric acid at 95% for 5 minutes, T4- mechanical scarification, and T5- immersion in hot water at 60 oC for 15 minutes. The data were analyzed in the SISVAR statistical program and the means were compared through the Tukey test at 5% probability. Seeds immersed in cold water for 48 h had the best performance in dormancy breaking.
