龙胆科观赏植物生理特性与育种技术综述

Review on the Gentianaceae Ornamentals Breeding and Cultivation Technology

  • 摘要: 中国拥有丰富的龙胆科植物种质资源,但研究活动基本集中在药用领域,观赏利用与育种技术研究尚未兴起。本文综述了国内外龙胆科植物观赏栽培和育种的历史与现状,分析它们栽培生理特性和繁殖技术,探讨分子标记辅助选择、种间杂交、单倍体细胞组培等育种技术的研究进展。提出了通过药花两用综合开发,温室栽培和不同海拔露地栽培相结合,跨区域种间杂交和倍性育种等手段促进国内观赏龙胆种植产业发展的建议。

     

    Abstract: The Gentianaceae germplasm resources of China are very rich. However, currently research activities focus on medicinal usage, breeding of new varieties and ornamental usage development are in scarce. The article summarized the history and present situation of Gentianaceae plants cultivation and breeding for onamental application; Their physiolgy characters of cultivation and propagation technology were analysed; The newly breeding technolgies that include molecular marker asist seclection inter species crossing and in vtro doubled haploid prodution were reviewed.To promote genetian industry development, it was suggested that to utilize one plants both as medicals and ornamentals, to combine greenhouse year-round cultivation and outdoor cultivation in several altitude, to integrate inter-species cross with very different region and utilize double haploid technology for new variety breeding.
