Popis:	The seeds of Albizia julibrissin are dormant because of their hard seed coat and they need pretreatment in order to germinate. In this research the effect of a) dry heating, at 30°C to 100°C for 10 to 60 min, b) chemical scarification with concentrated H2SO4 for 15, 30, 60, 90 or 120 min, c) mechanical scarification for 5 sec, d) seed soaking in warm water (30°C to 100°C for one to six hours) and e) seed soaking in tap water for one to six days, on seed germination were examined. The most successful treatment was chemical scarification in concentrated H2SO4 for 2 hours (germination percentage 99%). Soaking in 40 or 50°C warm water also resulted in high germination percentages (86 and 91%). The germination obtained after soaking in tap water for two days was also satisfactory (73%). All the above treatments also increased the germination rate as the overall germination was completed in less than six weeks.
