摘要
以紫薇岱宗2号品种当年生半木质化枝条和木质化枝条为试材,研究了扦插时期对插穗生根能力的影响,结果表明,半木质化枝条优于木质化枝条。通过对半木质化枝插穗生根过程进行形态学和解剖观察,表明插穗茎内无根原基,不定根原基为诱发型的,起源于维管形成层与初生射线的交叉处。
One - year - old semi - hard wood and hardwood of Lagerstroemia indica cuhivar Daizong 2 were used as materials for studying the rooting ability during cutting. The results showed that the rooting ability of semi - hard wood cuttings was better than that of hardwood cuttings. The morphological and anatomical structure of semi - hard wood cuttings was observed during rooting process. The observation results showed that there was no root primordium in cutting stem; the adventitious root primordium belonged to the induced type and originated from the cross region of vascular cambium and primary rays.
