- Abstract Seed dormancy is the limiting factor in the propagation of Leucaena leucocephala, a leguminous tree with wide important utilization. With the aim of obtaining the best treatment for breaking of seed dormancy in this plant, the present research was conducted. For this reason, three treatments:1 control, 2 soaking the seeds in cold water for 24, 48 and 72 minutes, 3 mechanical scarification: clipping of seeds around micropyle, clipping of seeds at distal end and sandpapering, and 4 soaking the seeds in sulfuric acid for 4, 8, 12, 16, 20 and 24 minutes were used. Results of the study revealed that regardless of soaking time, soaking the seeds in sulfuric acid resulted in the highest germination and seedling growth, followed by mechanical scarification and control, respectively. The lowest germination and early seedling growth was recorded when the seed soaked in cold water.
