Effect of pretreatments methods on the number of leaves growths of Acacia polyacantha seedlings. T1: immersion in cold water at room temperature for 24 hours, T2: immersion in hot water (100°C) for 5 minutes, T3: immersion in concentrated sulfuric acid (0.3 M H2SO4) for 20 minutes, T4: scarification by mechanically nicking using secateurs, and T5: control.
