摘要:

通过光学生物显微镜及Qwin图像分析系统，对人工繁育栽培的铁皮石斛各生长期植株的内生菌根进行了观察分析。结果表明:铁皮石斛具有典型的内生菌根；铁皮石斛根内共生菌不是其原有的，而是通过栽培基质传与铁皮石斛的根而共生。被真菌侵染的区域大，其植株生长茂盛，真菌对铁皮石斛的生长发育可能有促进的作用。

Abstract:

The roots of cultivated Dendrobium officinale with endomycorrhiza from Guangxi were observed using the Qwin image analysis system in different grwoth periods. The results showed that the roots of D.officinale had typical endomycorrhiza and the endophyte fungi came from their substrates and then co existed with D.officinale. Furthermore，D.officinale could grow better after the more endophyte fungi immigrated. Thus，endophyte fungi could increase the growth of D.officinale.

Key words: Endomycorrhiza Dendrobium officinale cultivation
