| 摘 要： | 研究了切除匍匐茎对鹅绒委陵菜克隆生长的影响.结果表明：切除匍匐茎使鹅绒委陵菜根部直径有增大趋势，而根长明显小于对照；在生物量分配方面，切除匍匐茎使其生物量投资偏向于地上部分，总生物量明显小于对照；此外，切除匍匐茎使鹅绒委陵菜的复叶数、复叶长度、基株高度在不同程度都有所升高.

| Abstract: | The research was carried out to investigate the response of clonal growth of the prostrate herb Potentilla anserina L.to stolon severing.The plant roots became wider,but the root's length was significantly short.The plants invested much more biomass to their above ground part and the total biomass was reduced as a result of stolon severing.The number and length of compand leaf were more and longer than these of control.The plant height of the ramet was higher than that of control as well. |
