中文摘要	研究了生长在四爪陆龟保护区荒漠-绿洲交错带处于不同生活史阶段(营养期和结实后期)的圆叶锦葵种群构件数量性状以及变化规律。结果表明:圆叶锦葵种群以结实后期植株各构件数量和生物量为多,其叶片数量是营养期植株的1.25倍;根、茎生物量则均超过了3倍以上;叶生物量之比为2.06。随着叶片数量增加,营养期植株中不同营养构件的生物量呈线性正相关关系,结实后期植株则呈幂函数正相关关系。结实后期植株中,果实生物量与根、茎生物量呈幂函数正相关关系,果实数量与二者呈线性正相关关系。不同生活史阶段圆叶锦葵种群构件具有同速和异速两种不同的表型可塑性调节。
英文摘要	Malva rotundifolia grows in oasis-desert ecotone in the Yili Testudo horsfieldi Nature Reserve. In this paper,the quantitative characters and change of organs of M. rotundifolia in different life cycles were researched. The results show that the number and biomass of organs at late fructification stage of M. rotundifolia population were higher than those at vegetative stage. Leaf number at late fructification stage was 1. 25 times of that at vegetative stage,root and stem biomasses were over three times,and the ratio of leaf biomass was 2. 06. With the increase of leaf number,there was a linear positive correlation among the biomasses of different organs at vegetative stage,but a power function positive correlation after fructification. There was a power function positive correlation between fruit biomass and root and stem biomass after fructification,but a linear positive relationship between fruit number and root and stem biomass. In different life cycles,there were two different phenotypic plasticity patterns of organs of M. rotundifolia population,i. e. the isogony phenotypic plasticity and allometry phenotypic plasticity.
