摘要: 桂花(Osmanthus fragrans Lour.)野生资源有非常丰富的性状和遗传变异,但目前被过度开发、破坏,导致分布范围急剧缩小,种群规模和数量锐减,生境片断化严重。以往的文献认为桂花起源于喜马拉雅山脉东段,即中国的西南地区;然而随着野生种群在湖南、浙江和福建等地被陆续发现,关于桂花自然分布的问题需要重新审视。作者在大量野外调研的基础上,结合前人研究结果,对桂花的自然分布和种群特征等进行了总结和概括,分析了野生资源与品种起源的关系,以期为桂花野生资源的有效保护和高效利用提供参考。

Abstract: Wild germplasm of Osmanthus fragrans Lour. have rich morphologic and genetic variations. However,due to excessive exploration and utilization in recent decades,the distribution range,size and number of natural populations decreased rapidly,and the habitats fragmented seriously. According to some previous references,O. fragrans originated from the east of the Himalayas i.e. the Southeast of China including Sichuan,Yunnan and Guizhou provinces. However,along with the discovery of natural populations successively in Hunan,Fujian and Zhejiang provinces,the natural distribution of this species need to be re-considered. In this paper,combining amount of field investigation discoveries and previous references,the natural geographic distribution and population characteristics were summarized and raised,and the relationship between the origin of cultivars and wild germplasm was discussed. These will provide a reference for the protection and utilization of natural populations.

Key words: Osmanthus fragrans, geographic distribution, population characteristic, cultivar origin, protection, utilization
