| 摘 要： | 莲瓣兰是分布于云南西北部、四川西南部和台湾的濒危兰花.本研究采用引种不同种群的莲瓣兰栽培在相同环境中的植株为实验材料,测定其形态性状并进行统计计算,分析莲瓣兰种群之间的形态变异以及亲缘关系.巢氏方差分析结果显示,莲瓣兰19个表型性状居群间方差百分比为22.162%,居群内方差百分比为77.838%,莲瓣兰形态变异主要来源于居群内;聚类分析显示保山施甸(SD),大理云龙形态(YL)较为接近,春剑贵州兴隆(XL)居群形态与莲瓣兰各居群差别较大,距离较远.研究结果可为莲瓣兰的类群划分、良种选育及野生资源的保护提供基础数据.

| Abstract: | Cymbidium tortisepalum is an endangered orchid distributed in northwestern Yunnan, southeastern Sichuan, and Taiwan.In the present paper, the pattern of morphological variation and the mechanism of variation formation and maintenance in C.tortisepalum were examined.Investigations on the morphological characters of C.tortisepalum revealed that 77.84% of total morphological variation was found within populations.This research improved current data on and understanding of the taxonomy, cultivation, and resource conservation of C.tortisepalum. |
