Abstract

Biomass allocation was size-dependent. Under soil nutrient, the plasticity of the leaf and reproductive allocation was "true" plasticity, the plasticity of stem allocation was "apparent" plasticity, which is dependent on plant size, but there was no plasticity in root allocation. Under soil water stress, the plasticity of root, leaf and reproductive allocation was "true". in response to population density, the plasticity of stem allocation is "true" plasticity, while the value of the stem allocation is consistent because of the trade off between the effects of plant size and population density. The biomass allocation strategy increases reproductive allocation but decrease leaf allocation with the decrease of soil nutrient, when compared at the same plant size. at lower soil water, the plant allocated more biomass to the root and leaf rather than to reproductive organ.
