摘　　要：[目的]探索桃砧木GF677高效硬枝扦插繁殖技术。[方法]以桃砧木GF677一年生枝条为试材,设置扦插基质、生根剂和插条粗度3因素3水平正交试验,研究不同因素处理对GF677硬枝扦插的生根率和成苗率的影响。[结果]在扦插基质为椰糠和珍珠岩的混合物(体积比为1∶2.5)、10 g/L生根粉蘸根、插条粗度为1.0~2.5 cm时,GF677的生根率和成苗率均最高,分别达到90.38%和40.38%。[结论]优化了桃砧木GF677硬枝扦插繁殖技术,为桃抗性专用砧木的推广和应用提供了研究基础。[Objective]Explore the efficient hardwood cutting propagation technology of peach rootstock GF677.[Method]The effects of different factors on the rooting and seedling rate of peach rootstock GF677's hardwood cuttings were studied by using GF677's annual branches as test materials and setting three factors and three levels orthogonal test of cutting substrate,rooting agent and cutting's diameter.[Result]The rooting rate and seedling rate of GF677 were the highest,reaching 90.38%and 40.38%,respectively,when the cutting substrate was a mixture of coconut bran and per⁃lite(volume ratio of 1∶2.5),10 g/L rooting powder was dipped in the root,and the cutting's diameter was 1.0~2.5 cm.[Conclusion]The results of this study optimized the hardwood cutting propagation technology of peach rootstock GF677,and provided a research basis for the promotion and application of resistance rootstock of peach.
