松嫩平原朝鲜碱茅无性系生殖器官构件的表型可塑性

在开花期从构件水平对松嫩平原碱化草甸朝鲜碱茅无性系种群分蘖丛各构件性状的表型可塑性,各功能构件生物量与丛径之间的关系,以及各功能构件生物量之间的关系均建立相应的模型进行了定量分析。结果表明：在开花期,朝鲜碱茅种群分蘖丛各构件性状具有较大的表型可塑性。朝鲜碱茅无性系种群各功能构件生物量与丛径之间的定量关系中,光合构件、有性生殖构件、营养繁殖构件以直线函数模型相关性最大,支持构件、非生殖构件以幂函数模型相关性最大;各功能构件生物量之间的定量关系均以直线函数模型相关性最大。

Phenotypic Plasticity of the Reproductive Organ Modules of Puccinellia chinampoensis Clones in Songnen Plain of China

The qunantitative analysis was conducted at module level on the biomass structure of modules in clonal population of Puccinellia chinampoensis,the relationship between modules'biomass and turf size,and the relationship between one module's biomass and another one's.The results showed that the flowering period,the tillers of Puccinellia tenuiflora population plexus of the component traits had greater phenotypic plasticity.Puccinellia functional clonal population biomass and plexus components quantitative rel...
