| 摘 要： | 以调查统计的方法研究了矮嵩草草甸和金露梅灌丛两种生境下鹅绒委陵菜无性系的形态特性，研究结果表明：矮嵩草草甸内的鹅绒委陵菜无性系绝大多数特征参数大于金露梅灌丛内，形态可塑性较显著，这与不同生境下的资源异质性特征密切相关。研究为生境适应假说提供又一例证。

| Abstract: | The morphological character of Potentilla anserina clone were studied by the method of investigation in Kobresia humilis meadow and Potentilla fruticosa shrub,respectively.Most parameters of Potentilla anserina clone in Kobresia humilis meadow were larger than those in Potentilla fruticosa shrub.The morphological plasticity of Potentilla anserina clone was significant in Kobresia humilis meadow,which was closely correlated with resource heterogeneity under different habitats.The study showed a new proof for habitat adaptability hypothesis. |
