Experimental Research on Grafting Propagation of Amygdalus ledebouriana Schleche

Objective Based on the observation of the survival rate and growth of Amygdalus ledebouriana Schleche by different grafting methods,this experiment is designed to screen out the best grafting method.MethodIn this experiment,Prunus triloba and Prunus armeniaca were used as rootstocks to analyze the survival rate of scion and the growth of shoots of wild almond by different grafting methods,time and sites.ResultThe results showed that the grafting of Prunus triloba was better than that of Prunus armeniaca;the survival rate of the cut-grafting was higher than that of the cleft grafting,bark grafting,tongue grafting and T-shaped grafting,and the cut-grafting method could be promoted on large area;the most suitable grafting time for wild almond was in spring and early autumn,specifically,in March and mid-August;the highest survival rate occurred when the grafting angle was between 15-30°.ConclusionThe best grafting for wild almond is to select Prunus triloba as rootstocks to graft in March or mid-August each year using cut-grafting method with the grafting angles between 15-30°.
