云南省番荔枝科资源植物多样性研究

Studies on Plant Diversity of Annonaceae in Yunnan Province

理清云南省番荔枝科植物的物种资源,为其资源保护和开发利用提供数据来源。结合最新发表的番荔枝科相关文献资料,对云南省番荔枝科植物属和种的组成、属的区系类型、物种丰富度、濒危等级及野生水果资源进行统计分析。结果显示:(1)云南省番荔枝科植物共有24属101种,其中瓜馥木属种类最多;(2)区系成分组成以热带亚洲(印度-马来西亚)为主要分布类型;(3)云南番荔枝科植物区系与广西番荔枝科植物区系是近亲关系;(4)极危种1种,濒危种7属12种;(5)有8个种具有开发利用价值。本研究结果可为云南省番荔枝科植物资源保护和该科野生水果资源开发利用提供参考资料。

Aim to clarify the species resources of Annonaceae in Yunnan Province and provide data for their conservation,development,and utilization.Based on the latest published literature on Annonaceae,the composition of genus and species,flora types of the genus,species richness,endangered status,and wild fruit resources of Annonaceae in Yunnan province were statistically analyzed.The results showed that:(1)there were 101 species belonging to 24 genera in the Annonaceae in Yunnan province,among which Fissistigma was the most abundant genus;(2)the floristic composition was mainly tropical Asia(In-dia-Malaysia);(3)the flora of Annonaceae in Yunnan was closely related to that in Guangxi;(4)one critically endangered species and 12 critically endangered species belonged to seven genera;(5)eight species had the value of development and utilization.The results could provide information for plant resource protection and wild fruit-resourced development and utilization of Annonaceae in Yunnan Province.
