繁殖矮化中间砧苹果苗时,把矮化砧的接芽芽接于海棠或野苹果基砧上,成活率均较低。77年,芽按M_4、M_7和M_9共1446株,成活955株,成活率只有66％。1978年试用了单芽切腹按和带接芽切按两种方法,表明这两种方法有一定优越性,在繁殖矮化中间 Breeding dwarfing the middle anvil apple seedlings, the dwarfing anvil bud sprouting on Begonia or wild apple root anvil, the survival rate is low. In 1977, a total of 1446 M_4, M_7 and M_9 buds survived and 955 survived, with a survival rate of 66%. 1978 trial of a single-celiac incision and cut with the bud by two methods, indicating that these two methods have some advantages in the middle of breeding dwarfing
