钻天柳嫁接插条法育苗研究

目的]通过嫁接插条法进行钻天柳繁育。方法]以大白柳、朝鲜柳和旱快柳为砧木,钻天柳雄、雌株为接穗,进行不同砧木与钻天柳的6个组合嫁接插条试验,并设置砧木为朝鲜柳、旱快柳,接穗为旱快柳、朝鲜柳的4个对照组合。结果]在10个组合中,仅朝鲜柳作砧木,接穗为钻天柳雄、雌株的2个组合成活,成活率分别为25.0%和27.0%。结论]该研究对钻天柳的保护及大规模繁育有一定的借鉴意义。

Study on Seedling of Chosenia arbutifolia by Grafting Cuttings

Objective]To breed Chosenia arbutifolia by grafting cuttings.Method]Using Salix maximowiczii,S. koreensis and S.matsudana as rootstocks and the male and female C.arbutifolia as scion, the grafting and cutting experiments of C.arbutifolia were carried out.At the same time,using S.koreensis,S.matsudana as rootstocks and S.matsudana,S.koreensis as scions to make four contrasts.Result]In ten combinations, the two combinations which used S.koreensis as rootstock and the male and female C.arbutifolia as scions survived,the survival rate was 25.0% and 27.0%,others did't survive.Conclusion]The study has reference meaning to the protection and large-scale breeding of C.arbutifolia.
