大头茶属植物研究进展

Research advances of Polyspora Sweet(Theaceae)

大头茶属(Polyspora Sweet)为山茶科常绿树木,共50种,主要分布于南亚和东南亚地区。大头茶属植物均具有较高观赏价值,可作为热带和亚热带地区的园林绿化树种,部分种类兼具食用和药用价值。该文在对大头茶属种质资源和应用情况简要介绍的基础上,对其系统演化及分类、繁殖特征、生理特性、生态习性、育苗技术、化学成分及药理活性等方面的研究进展进行了较为详细的综述,提出了目前研究中存在的问题,并对今后的研究方向进行了展望,指出未来应扩大大头茶属的研究范围和种类,加强种质资源搜集、系统发育、遗传多样性等研究,重点关注大头茶属的引种栽培与种质创新,充分发掘其药用价值,开展临床转化和药物研制工作,可为合理开发利用野生大头茶属种质资源提供理论依据和研究思路。

Polyspor a Sweet are evergreen tree of Theaceae with 50 species,mainly distributed in South Asia and Southeast Asia.Polyspor a have high ornamental value,can be used as landscape trees in tropical and subtropical regions.Some of them have edible and medicinal values.Based on the brief introduction of the germplasm resources and application of the genus Polyspor a,the research progress of its systematic evolution and taxonomy,reproductive characteristics,physiological characteristics,ecological habits,seedling technology,chemical components and pharmacological activities were reviewed in detail.This review point out that in the future,we should expand the research scope and species of the genus,and strengthen the germplasm resources collection,phylogeny,genetic diversity and so on.We should pay more attention to the introduction,cultivation,and germplasm innovation of the genus,and fully explore its medicinal value,and carry out clinical research.This review paper will provide theoretical basis and reference for further research of Polyspora plants.
