[目的]研究不同基质对多肉玉珠帘叶插的影响.[方法]以玉珠帘为材料,采用叶插的方法,研究了不同基质、不同生根剂与同一生根剂不同时间处理对玉珠帘根和芽的影响.[结果]不同扦插基质处理玉珠帘对其成活率、出芽率、生根率的影响差异性不显著,但是对其根和芽的生长影响差异性显著.同一激素不同处理时间对玉珠帘叶基部处理时,浸泡时间越长对其生根发芽的抑制作用越显著,IBA处理的玉珠帘生长差异性显著,当处理时间为40 s时整体效果最理想,此时玉珠帘的生根出芽情况较理想.不同激素处理中,清水对照效果最好,6-BA+NAA次之,而6-BA效果最差.[结论]适宜的激素浓度和处理时间可以显著提高玉珠帘的发芽率、芽长、根长,从而提高玉珠帘的扦插成活率.%[Objective]To research the effects of different substrates on cuttage of succulents Sedum morganianum. [Method] With Sedum mor-ganianum as the experimental material,the effects of substrate,rooting agent and treatment time on the Sedum morganianum roots and buds were researched by leaf cutting method. [Result]Different cutting substrates treatments had no significant differences in survival rate,germination rate and rooting rate,but had significant differences on the growth of roots and buds. When Sedum morganianum leaf base was processed by the same hormone under different treatment time,longer soaking time had more significant inhibitory effects on rooting.Sedum morganianum in IBA treat-ment had significant differences in growth. When the treatment time was 40 s,the overall effect was the most ideal,and the rooting and budding situation was relatively ideal. Among the different hormone treatments,clean water control showed the best effects,followed with 6-BA—NAA;and the effects of 6-BA were the worst. [Conclusion] Proper hormone concentration and treatment time significantly enhanced the germination rate,bud length and root length of Sedum morganianum,so that the cutting survival rate was enhanced.
