粗糠树种质资源收集及育苗技术研究

Germplasm Resources Collection and Breeding Techniques Research on Ehretia dicksonii Hance

粗糠树(Ehretiadicksoniihance)属于紫草科厚壳树属,是一种优良的乡土树种,目前在自然界濒临灭绝,亟待保护、开发、利用。对粗糠树种质资源调查、收集、保存及育苗技术开展研究。对粗糠物候期、生物学特性,抗逆性、进行了观测记录,对优良单株进行了标记、繁育。

Ehretia dicksonii Hance,belonging to Boraginaceae,Ehretia,is a super native tree species.At present,it’s near extinctive and needs to be protected,developed and utilized urgently.This paper investigated,collected and preserved the germplasm resources of Ehretia dicksonii Hance,and researched the breeding techniques.Besides,it observed and recorded the phenological phase,biological characteristics and stress-resistance,marked and bred superior individual plants.
