This article presents the results of studying the effects of types of grafting scion and grafting methods on the survival and growth of grafting unions of Docynia indica. The experiment were arranged by 2 factor and ramdomized approach with 6 grafting formulas (2 methods of grafting (side veneer grafting, cleft grafting) and 3 types of grafting scion (semi-wooded scion, scion with bud, wooded scion)). The research results show that the combined effect of two grafting factors does significantly affect the survival. However, does not significantly affect the growth of the grafting unions. The individual grafting factor has signifcant effects on the survival and growth of the grafting unions. The highest survival rate is 72% by appying method of side veneer grafting with type of wooded scion. The average diameter and height of the buds of the grafting unions are achieved by applying method of cleft grafting and scion with bud.
