摘　　要：为探究砧木种类和规格对‘大渔’樱嫁接苗成活及生长的影响,本研究以3种不同地径(小规格、中规格和大规格)的‘中国红’樱、‘小乔’樱和‘广州’樱作砧木,以‘大渔’樱当年生健壮枝条为接穗,定期测定各组合嫁接苗的成活率、愈合良好率和株高等指标。结果表明,采用6~9mm的‘中国红’樱嫁接‘大渔’樱效果最佳,该组合嫁接成活率和愈合良好率分别为98.00%和93.10%;砧木品种和规格对‘大渔’樱嫁接苗株高和接口径的生长无明显影响,其中16~20mm‘中国红’樱的嫁接苗株高最大,为289.5cm,10~15mm‘广州’樱的嫁接苗接口径最大,为16.77mm;‘大渔’樱嫁接苗株高和接口径均在2—4月生长最快,部分砧穗组合的嫁接苗接口径出现两个生长高峰。综合成活率和株高等指标表明,‘大渔’樱的嫁接砧木宜选择6~9mm的‘中国红’樱。To investigate the effects of rootstock types and specifications on survival and growth of Cerasus×kanzakura‘Tairyo-zakura’.The survival rate,good healing rate and height index of C.campanulata‘Zhongguohong’,C.speciosa‘Xiaoqiao’,and C.yunnanensis‘Guangzhou’cerasus with 3 different ground diameters(small,medium,and large)were measured regularly,and the current year strong branches of Cerasus×kanzakura‘Tairyo-zakura’cerasus were used as scions.The results showed that 6-9 mm C.campanulata‘Guangzhou’used to graft C.×kanzakura‘Tairyozakura’had the best effect,and the survival rate and good healing rate were 98.00%and 93.10%,respectively.The variety and size of rootstocks had no significant effect on the growth of the grafted seedling height and diameter of C.×kanzakura‘Tairyo-zakura’,among which the grafted seedling height of 16-20 mm C.campanulata‘Zhongguohong’was the largest(289.50 cm),and the grafted seedlings diameter of 10-15 mm C.yunnanensis‘Guangzhou’was the largest(16.77 mm).The height and diameter of the grafted seedlings of C.×kanzakura‘Tairyo-zakura’grew the fastest from February to April,and there were two growth peaks in the grafted seedlings diameter of some rootstock and scion combinations.The overall survival rate and plant height index indicated that the grafted rootstock of C.×kanzakura‘Tairyo-zakura’was 6-9 mm in length.
