中国梅的变异与分布研究

通过文献阅读、标本查阅及实地考察，发现了梅的一些变异类型。提出了梅的地理分布格局，对梅分布的历史迁作的探讨。种、滇、藏交界的横断山区是梅的自然分布中心，另外还有一些亚中心；在对种群数量和变异类型研究的基础上，确认梅的自然分布中心即梅的变异中心。

Studies on the Variation and Distribution of Prunus mume Sieb. et Zucc

Some variation types ofPrunus mume were found through reference reading, specimen examination and on-the- spot expeditionary survey. A natural distribution pattern of the species was revealed, and the historical changes of which were also discussed. Northwestern Yunnan, Southwestern Sichuan and Southeastern Xizang (Tibet) Autonomous Region were considered to be its distribution centre, and some subcentres were also recognized.Based on the studies on its variation types and mass numbers, it is suggested that the natural distribution centre is also the variation centre.
