In this paper,quantitative analysis was conducted at module level on the biomass structure of modules in clonal population of Puccinillia chinampoensis,the relationship between modules' biomass and turf sizes,and the relationship between one module' biomass and another one's.Based on these,the corresponding models of these relationships were established.The results showed that the regularities on the biomass of all functional modules and their ratio were the same at earing stage and at vegetative stage after fruiting.There existed linear correlation between functional modules and turf sizes at earing stage,and exponential correlation at vegetative stage after fruiting.Among all quantitative relationship models,only the one between photosynthesis modules and supporting modules was linear function at earing stage and exponential correlation at vegetative stage after fruiting.The relationship models between any other two functional models were all exponential correlation at two stages.
