香果树保护生物学研究进展

Research Progress on Conservation Biology of Emmenopterys henryi

香果树Emmenopterys henryi是第四纪冰川孑遗植物之一、国家二级保护植物。本文从生物学、生态学以及生理特性、遗传多样性和繁育技术等方面综述了过去40年国内外学者对香果树的保护生物学研究的成果,梳理了前人研究的空白与不足。本文认为,目前对于香果树花芽分化,雌、雄配子体和胚胎发育的研究仍存在空白,缺少针对香果树与其他物种种间关系的研究,今后应借鉴森林大型监测样地的研究方法,综合各学科的技术手段对香果树开展长期系统的监测研究,以期更深入地了解香果树的濒危机制,做好香果树的保护工作。

Presentation was made on achievements of researches on the conservation biology of Emmenopterys henryi in the past 40 years in terms of biology,ecology,physiological characteristics,genetic diversity,and breeding techniques.It demonstrated that there was still challenges in the research on flower bud differentiation,male and female gametophyte and embryo development of E.henryi,as well as on the interspecific relationship between E.henryi and other species.Propositions were put forwarded to better protection of the rare species by large-scale permanent sample plots monitoring with different research methods.
