Biomass structure and production pattern of Hordeum brevisubulatum clonal modules under cultivated condition in the Songnen Plains

Abstract

Abstract: Hordeum brevisubulatum is a typical clonal plant of grass family with short rhizome.In the Songnen Plains of China,the ramets of the clones were made up of stemming tillers and rosette seedlings by the end of the growing season.According to age class of the vegetative generations of tiller node,the tillers of the clones were divided into three age classes,and the seedlings were divided into four age classes.The age structures of their biomass under cultivated condition for two years were all of expanding types.The productivities of the ramets,both of the tillers and of the seedlings in the 1st age class of the clones,were the highest,and decreased with the increasing age class by the end of the growing season.The diameter of the tufts was the important quantitative index to measure the special size of the clones,and the number of the ramets could be useful to measure the growth of the clones.Statistical results showed that the total biomass and the biomass of the tillers,seedlings and rhizomes were all increased by power function with the size of tuft diameters and the number of total ramets,and the correlations were all significant.
