The beginning of the reforestation being assisted germination, it seems essential to know if the seeds of different tree species germinate without problems or if they have some problems, for in finding appropriate methods of germination. This study aims to stimulate the seeds germination of <> in the experimental plantation of University President Joseph Kasavubu at Km 8 Boma site,according they are soaked in hot water at 90 0 C or in water at ambient temperature (25 0 C). Thirty seeds were planted in each of three blocks (floors) chosen, and three samples were taken at 20 days interval. Data on the seeds number taken from each treatment and each block were statistically analyzed in using the software R. The results show that hot water at 90 0 C over stimulated seeds germination (germination rate of 80% ), followed by water at 25 0 C (germination rate of 70%) and the control (untreated seeds, 50%). The properties of water at 90 0 C exceeds that of water at 25 0 C to stimulate germination, better, to break dormancy. It is therefore possible to subject the seeds of << Albizia lebbeck >> to different treatments and get good results.
