摘要: 以红香椿的根条和枝条为试材 ,采用正交试验设计进行扦插繁殖育苗试验 ,结果表明 :香椿根条扦插优于枝条扦插 ,长插穗扦插效果优于短插穗 ;两种插条生根部位有所不同 ,枝插条是愈伤组织生根 ,根插条则以皮部型生根为主 ,少部分为愈伤组织生根。根条和枝条扦插繁殖可用于香椿大规模育苗生产 ,采用直径 0 .5cm以上的根和直径 0 .8cm以上的枝 ,于 3月底扦插 ,剪截长度分别为 8cm、12cm ,扦插前插条下端用HL4 3生根剂分别处理 15~ 2 0s(秒 )、5s(秒 ) ,插于沙床 ,生根率达 94 .3%。

Abstract: Using root cutting and shoot cutting,by means of the orthogonal design propagation of Toona sinensis was carried out. The results showed that root cutting was superior to shoot cutting,and long cutting was better than short cutting for propagation. There were some difference in rooting positions between the root cutting and the short cutting,Adventitious roots developed from callu and corium for the shoot cutting and root cutting respectively. Cutting propagation using root and shoot cutting could be us...
