| 摘 要： | 通过西双版纳自然保护区勐养保护区栽培砂仁和野生缩砂密的实地调查 ,比较了二者的形态特征 ,以及考证了植物分类学上缩砂密是砂仁变种的确立过程后认为 :缩砂密是我国云南南部地区、广西、广东及毗邻国家山地广泛分布的野生类型 ,其个体之间的差异明显 ,表现出多态性 .砂仁集中栽培于广东西南部 ,尽管个体之间也有差异 ,但其变异范围包含在缩砂密的变异范围内 ,是从缩砂密中选育出来的栽培类型 .二者之间的差异属于种群内的多型性 .缩砂密种群内丰富多样性为各地选育株系奠定了基础 .

| Abstract: | Based on the field investigation in Mengyang Nature Reserve of Xishuangbanna, the morphological characteristics of cultivated Amomum villosum and wild A. villosum var. xanthioides were comparatively studied. It is claimed that A. villosum var. xanthioides is a wild type widely distributed in southern Yunnan, Guangxi and Guangdong of China and the neighboring mountain countries. The diversity among its individuals plant is quite significant. Amomum villosum is a cultivated type with low diversity and cultivated in southwestern Guangdong which was selected from A. villosum var. xanthioides through a long period of cultivation. The difference between these two types are believed to be the polytypism of population. The diversity of A. villosum var. xanthioides provides a basis for the selection of new strains. |
