摘　　要：比较低温处理下不同砧木表型差异、嫁接方法和嫁接叶龄对嫁接成活率的影响,为筛选辣椒耐低温砧木和优化辣椒嫁接体系提供依据。结果发现,野生茄子S2的耐低温能力较强,可以作为辣椒嫁接耐低温砧木;在砧木二叶一心和接穗三叶一心时,采用劈接法嫁接成活率最高。研究结果为提高春提早和秋延后设施栽培辣椒植株的耐低温能力提供了实践依据。In this paper,we compared the effects of phenotypic difference of different rootstocks,grafting methods and grafting leaf age under low temperature treatment on the survival rate of grafting,aiming to provide a basis for screening low-temperature tolerant rootstocks and optimizing the grafting system of pepper.The results showed that wild eggplant S2 had a high tolerance to low temperature and could be used as a low temperature tolerant rootstock for pepper grafting.The highest survival rate of grafting was achieved by the splitting method when the rootstock was two-leafed and the scion was three-leafed.The results of the study can be a practical basis for improving the low-temperature tolerance of pepper plants in early spring and postautumn facility cultivation.
