Dynamics of reproductive allocation of reproductive tillers in Stipa baicalansis populations on the Songnen Plains,China

摘要：

Reproductive allocation ( RA) is the biomass ratio of reproductive organs to total biomass in all assimilative resource of a plant individual.Individual is plastic in size due to the difference of the microenvironment.The plasticity follows certain rules and shows the regulation in growth and allocation at the population level.Stip a baicalansis, a perennial grass, is usually the constructive or companion species of communities in meadow steppe regions in China ( Li, et al.,2003 ).The objective was to find the rules of the relationship of RA and height, biomass of tiller in different growing stages, which provided scientific accumulation to further research of reproductive ecology.
