The Effect of Pruning on Plucking Scion of Mother Plant of Acacia Species

Shooting trial was conducted by lopping and pruning for plucking scion of mother plant of three tropical Acacia species. The result was shown that the way of cutting height from 40～50 cm and saving 2～3 pieces of leaves at the base of trees through pruning would increase the amount of cuttings and improve shooting capability.It could not increase number of shooting and amount of cuttings to enhance cutting height.Pruning from the bottom of branch would impact the growth of cutting wood.If cuttings at 20～30 cm high were used which would seriously influence the shooting and growth of cutting wood.Except for low cutting stump,there is no evident effect on the survival of cutting by middle and high cutting stump.
