摘要
青钱柳是我国特有的单种属乔木及国家重点保护濒危植物之一,是极其重要的珍稀木本植物资源.近年来由于其具有降血糖、降血压、降血脂,增加机体免疫力、抗氧化、抗衰老等诸多功效,尤其是其具有修复受损胰岛β细胞作用的特性而受到国内外广泛关注.然而青钱柳种子败育严重并具有深休眠性,有性繁殖系数很低,其野生资源的稀缺和繁殖困难使这一资源的利用受到了极大的限制.围绕青钱柳种质资源筛选、有性繁殖、无性繁殖、定向培育等方面的研究现状进行分析,总结了目前繁育技术研究过程中存在的无性繁殖难生根问题和组织培养过程中的污染、褐化、玻璃化等问题,提出了预期的解决方案和未来的研究方向,旨在为青钱柳进一步的资源培育提供参考.
Abstract
As one of the national key protected and endangered plants in China,Cyclocarya paliurus is a unique single species genus tree,which is an extremely important rare woody plant.It can be used for lowering blood sugar,blood pressure,blood lipids,enhancing the body's immunity,antioxida-tion,and anti-aging,especially repairing damaged pancreatic islets β.So its characteristics have at-tracted widespread attention in recent years.However,the seed of Cyclocarya paliurus with severe abortion and deep dormancy,has a very low coefficient of sexual reproduction.Its effective utilization was greatly limited in the resource scarcity and reproduction.An analysis had been conducted in germ-plasm resource screening,sexual reproduction,asexual reproduction,and targeted cultivation of Cyc-locarya paliurus.And some unresolved issues were summarized,such as the difficult rooting,asexual reproduction,pollution,browning,and vitrification during tissue culture.Expected solutions and fu-ture research directions had been proposed,aiming to provide reference for further cultivation of Cyclo-carya paliurus.
