极小种群野生植物毛果木莲研究进展

Research Progress on Manglietia ventii Listed in Plant Species with Extremely Small Populations

毛果木莲是云南特有的极小种群野生植物,主要分布在滇东南地区,由于自然生境持续性恶化、人类过度采伐利用以及自身繁育能力衰退等原因,导致其种群的个体数量大幅下降。通过实地调查与文献梳理,系统回顾了毛果木莲的系统分类学、生态学、繁殖生物学、遗传多样性、濒危机制及资源保护等多方面国内外研究现状。并对未来的研究方向进行了展望,应加强毛果木莲基础特性研究,探寻毛果木莲的传播途径及深化资源开发与利用等。旨在为毛果木莲的种质资源保护和可持续利用提供理论支持,还可为其他极小种群野生植物的保护研究提供参考。

Manglietia ventiiis an extremely small population of wild plants endemic to Yunnan. It is mainly distributed in Southeast Yunnan. Due to the continuous deterioration of natural habitats,excessive logging and utilization of human beings,and the decline of their breeding ability,the number of individuals in the population has decreased significantly. Through field investigation and literature review,the research status of M. ventii in the domestic and overseas in systematics,conservation ecology,reproductive biology,genetic diversity,endangered mechanism and resource protection were systematically reviewed. And the future research direction is prospected. We should strengthen the research on the basic characteristics of M. ventii,explore the transmission route of M. ventii and deepen the development and utilization of resources. The purpose is to provide theoretical support for the protection and sustainable utilization of germplasm resources of M. ventii,and also provide reference for the protection of other plant species with extremely small populations.
