| 英文摘要 | Ten clonal units of carex pseudocuraica growing in four different microhabitats (perennial flooded ditch water, perennial flooded ditch sediment, seasonal flooded ditch sediment and perennial flooded soil) of the sanjiang plain, northeast china, were collected randomly for phenotypic plasticity analysis. iron content, chemical and physical properties of substrates and the total fe of nine plant modules were measured as well. the results show that the performance of the c. pseudocuraica is affected by the microhabitat, with the greatest performance score in perennial flooded ditch water, and the lowest in perennial flooded soil. the biomass allocation indexes indicate that much more mass is allocated to stems and roots to expand colonization area. the distribution of the total fe in plant modules appears as pyramids from the tip to the root, while marked differences are observed in the distribution proportion of sterns, tillering nodes and roots that are allometrically growing. iron transfer from substrates to the plant is mainly controlled by the substrate type. the differences of iron distribution and transfer in the plant in different microhabitats are attributed to the iron contents of the substrates as well as the phenotypic plasticity of the plant. |
