| 摘要: |
| 为了解决樱桃传统嫁接中存在的接穗贮藏难、受季节限制、砧木细而接穗大等问题，并对其在传统栽培过程中积累的病毒、类病毒进行有效脱毒,采用樱桃组培苗微型嫁接技术，研究了接穗大小、嫁接处理方式、组培苗继代时间、不同砧穗组合等因素对嫁接成活率的影响。结果表明，进行樱桃组培苗微型嫁接时，接穗大小为茎尖+2片叶（约1 cm）、组培苗继代35 d左右、嫁接时采取先嫁接后生根方式，其嫁接成活率和成苗率相对较高，嫁接成活率最高可达84%；接穗与砧木的亲和性越好，嫁接成活率越高，在供试樱桃品种中，以Gisela-5×红鲁比的亲和性最好，嫁接成活率达83%。 |

| Abstract: |
| In order to solve the problem in traditional cherry grafts,such as scion store difficulty,the season limit,the thin stock but the big scion and so on,and to eliminate the virus,the technique of micro grafts of cherry was used to study the effect of micro grafts,like the scion size,culture day of tube-plant,the processing mode,and combination of scion and stock on survival percentage.Results indicate that when taking grafting with the technique of micro grafts of cherry,the best scion size is the stem point +2 pieces of leaves (about 1 cm);the best tube culture plant for about 35 days;it is best that taking root after grafting.All these could improve survival rate,and the highest survival percentage could reach 84%;the larger the amicable number of different scion and stock is,the higher the survival percentage is;in all of the tested cherry varieties,the combination of Gisela-5 and Honglubi is highest,and the survival percentage can reach 84%. |
