摘要
对山桐子硬枝和嫩枝采用激素处理进行扦插繁殖试验,结果表明:山桐子在常规条件下硬枝、嫩枝扦插很难生根,但通过激素处理,硬枝、嫩枝扦插繁殖是可行的。在全封闭条件下,激素浓度、激素种类、插穗部位是影响山桐子硬枝扦插生根的主要因素,硬枝扦插试验平均生根率为21.34%;插穗部位、扦插时间、激素种类、插穗长度等因素是影响山桐子嫩枝扦插生根的主要因素,嫩枝扦插试验平均生根率为28.15%。试验观察结果显示愈伤组织的形成与生根没有必然联系。
Experiment was conducted on reproduction of ldesia polycarpa by hard-wood and softwood cuttings treated by hormones. The result showed that it was difficult for hardwood and softwood cutting to root under natural condition, but it was feasible for them by treatment of hormone. Under closed conditions, densities and kinds of hormone, cueing positions were the main factors to influence rooting of hard-wood cuttings, which had mean rooting rate of 21.34%. Cutting position, planting date, kinds of hormone and length of cuttings were the main factors to influence rooting of softwood cuttings, which had mean rootng rate of 28.15%. Experiment indicated that there was no relationship between callus tissue and rooting.
