摘　　要：为提高椿寒樱嫁接育苗成活率,分别以3种不同地径规格的‘中国红’樱(Cerasus campanulata‘Zhongguohong’)、‘小乔’樱(C.speciosa‘Xiaoqiao’)和‘广州’樱(C.‘Guangzhou’)为砧木进行了嫁接试验,共设置9个处理,对椿寒樱嫁接苗成活率、株高、接口径、高径比和嫁接口愈合情况进行了分析。结果表明:采用‘中国红’樱砧木的成活率较高,砧木地径增大在一定程度上可提高嫁接成活率,各处理嫁接苗生长良好,存活率与成活率相差无几;观测期结束时9个处理的株高、接口径和高径比无显著差异;砧木地径大小能影响嫁接苗嫁接口的愈合速度,地径越大愈合情况越差。因此可优先选用地径1.0~1.5cm的‘中国红’樱作椿寒樱嫁接繁殖用砧木。In order to improve the survival rate of grafted seedlings of Cerasus‘Introrsa’,the grafting experiments were carried out with Cerasus campanulata‘Zhongguohong’,C.speciosa‘Xiaoqiao’and C.‘Guangzhou’of three different ground diameter specifications as rootstocks.A total of nine treatments were set up to analyze the survival rate,plant height,graft diameter,height-diameter ratio and graft healing of grafted seedlings of Cerasus‘Introrsa’.The results showed as follows:the survival rate of Cerasus campanulata‘Zhongguohong’rootstock was higher,and the increase of rootstock diameter could improve the survival rate of grafting to a certain extent;the grafted seedlings of each treatment grew well,and the survival rates were almost the same.At the end of the observation period,there was no significant difference in plant height,graft diameter and height-diameter ratio among the nine treatments.The ground diameter size of the rootstock could affect the graft healing speed of the grafted seedlings,and the larger the diameter was,the worse the healing was.Therefore,Cerasus campanulata‘Zhongguohong’with ground diameter of 1.0-1.5 cm can be preferentially selected as rootstocks for grafting and propagation of Cerasus‘Introrsa’.
