Abstract

Terrestrial biomass and reproductive allocation characteristics of Sophora alopecuroides L. in Ili River valley.

Abstract

Objective: The purpose of this study is to grasp the plant reproduction and phenotypic plasticity plant material production and distribution of the inner link and variation. Method: A large samples from the Ili River valley wetlands were applied to conduct a systematic analysis of the population reproduction of Sophora alopecuroides L. Result: The results showed that the biomass of each reproductive ramet of S. alopecuroides population was (31.78±17.23) g; the biomass and number of pods were (4.37±2.55) and (47.30±24.49) respectively; the biomass and number of seeds were (3.08±2.13) g and (121.30±92.83) respectively; reproductive allocation 1 (RA1) and RA2 were (14.87%±6.34%) and (10.23%±5.04%) respectively at the seed ripening stage. The maximum in the observed phenotype data of each reproductive module were 6.1-12.9 times more than the minimum. There were two different regulations of phenotype plasticity in reproductive ramets of S. alopecuroides L. population at the same time, which were processes of increase/decrease for the isogony and allometry. Conclusion: The results of this study will effectively control the grassland and cropland ecosystems ecological invasion of S. alopecuroides L. and provide basic theories for rational development and application of that plant.
