干旱胁迫对蕨麻克隆构件的可塑性反应

Plasticity of Clonal Architecture in Response to Drought Menace in the Stoloniferous Herb Juema

研究了匍匐茎克隆草本植物蕨麻原变种(PotentillaanserineL.var．anserina)对干旱胁迫(即聚已二醇6000的浓度为0、5％、10％、15％、20％,10个重复)的表型可塑性:随着聚已二醇6000浓度的增加,实验植物的生物量显著减小;死亡率上升;基株叶片数目、基株叶片长度、基株叶片宽度具有显著的株间差异,呈二次曲线变化。因而在高寒地区的生态恢复中具有重要的意义。

Studied on the stoloniferous herb Juema plasticity menace （the concentration of PEG6000 is 0, 5%, 10%, of clonal architecture in response to drought 15%, 20%, 10 repeats）： with increase the concentration of PEG6000, the output of experiment plant reduces markedly; death rate goes up; Leaf number of genet, leaf length of genet, leaf width of genet have marked difference among individual plant, its change shows Conic, which has important significance for zoology comeback in the high cold area.
