STUDY ON THE GRAFTING TECHNIQUE OF INDUCING ROOT FROM SCION IN MASSON PINE

The grafting technique of inducing-root from scion is reported in this paper.After grafting,we put some soil around the base of the seedling stock.Then the induced scion starts to root and grow up.Both the grafting survival and its rooting rate surpassed 70%.There are many merits in using this technique,i.e.the wound between scion and stock healed completely and the grafted tree grew well,the position of the crown is lower than that of the tree before and the scope of fruitness expands.The root could be induced from the base of the scion and there is no affinity between scion and stock in the later stage of its growth.This is a new technique in clone breeding of masson pine and it could be used in practice.
