Abstract:
On the basis of the field investigation,the morphological plasticity and ecological strategy of Qiongzhuea tumidinoda clones under different levels of water resource supply were studied in the paper.The results showed that:It is obvious that the morphological plasticity of Qiongzhuea tumidinoda clones under conditions of different water resource supply.Clones under the high level of water resource supply had long and thick spacers and large biomass and the height,diameter,branching length,branching angle,leaf area of ramets were also great.Ramets density and total spacer length,however,were less.Clonal growth of Qiongzhuea tumidinoda under the low level of water resource supply seemed to allow a foraging strategy and increased the probability of ramets growing in favorable microhabitat in order to acquire the relative abundant water resource and keep away from a site of less water resource.
