鹅绒委陵菜（Potentilla anserina）生长特征

以调查统计的方法研究了矮嵩草草甸内鹅藏委陵菜无性生长特征。研究结果表明：匍匐茎只有1条的鹅绒委陵菜最多，占52.86%，匍匐茎有4条的鹅绒委陵菜只占4.29%，同一鹅绒委陵菜无性系中，随着匍匐茎数目的增多，分株数，间隔子数，茎总长和匍匐茎比节间重变小，分株一般在第二级或第三级最高，末级较高；间隔子一般以第二、第三或第四级为最长，最末一级较长，第一级最短，随鹅绒委陵菜匍匐茎数目的增多，用于繁殖的匍匐茎和分株的干重比例逐渐增加。

The clonal growing characteristic in the stoloniferous herb,Potentilla anserina

The characteristic of clonal plant, Potentilla anserina were studied in alpine Kobresia humilis meadow by investigation and statistics in this paper.The results are as followed. P.anserina with one stolon is the most and its proportion is 52.86%.The proportion of P.anserina with four stolons is only 4.29%.The ramet number,spacer number,total stolon length and specific stolon internode weight are decreased with the increase of stolon number in P. anserina clone.The second or third ramet are always the highest and the end ramet is higher.The second,third or fourth spacer are the longest and the end spacer is loner while the first one is always the shortest.The total dry weight of the clone is increased slowly while the dry weight proportion of stolons and ramets for reproduction are increased with the increase of stolon number in P.anserina clone.
