Preliminary Exploration of Technology Experiment for Grafting Kernel Apricot on Prunus sibirica
The scions of three kernel apricot varieties L-21-01,TN-QN and No.23 were grafted on Prunus sibirica root-stocks with different ground diameters(1.1-1.9 cm,2.0-2.9 cm,3.0-3.9 cm,≥4.0 cm)by bark grafting,cleft grafting and side cutting grafting.The results showed that the survival rate of grafting L-21-01 variety on the rootstock with the ground diameter≥4.0 cm by bark grafting was the highest.But the bark grafting had higher requirements for root-stock,scion and technology,and that was more suitable for the rootstock with larger ground diameter.
