Harper′s (1977) modular organism, considering the assemblage of Pleioblastus maculata in the habitat as a clone population, the dynamics of clonal propagative modules and the modules with age class genet of and density of ramets were studied in this paper.

Differences in the number of rhizome producing new shoots, the survival rate of new shoots,the basal diameter of new shoots and branch of 1-year-old bamboo between the presence and the absence of mother ramet in Neosinocalamus affinis were compared in order to explore the contribution of mother ramet to clonal propagation and branching of 1-year-old bamboo.

The specific goal of this study was to determine if there is a trade-off between sexual and clonal reproduction in H.

Rhus typhina is a kind of typical woody clone plants,which can establish a certain amount of single dominant community by clonal reproduction on low hills,farmland and both sides of roads in northern China.
