Asexual reproductive characteristics of wild Dichnondra repens in Southwest China

The temporal dynamics, patterns and space configuration of the asexual components of wild Dichondra repens (SD200310, SD200411, GD200504 and SD200304) were studied. The results indicated that 1) main stem growth rate declined over the time, the space expansion depended on the contribution of source strain, early ramets and leaves; 2) the variation of energy demand from plant migration growth and stem/leaf expansion resulted in the differences of clonal growth pattern and the distribution of biomass components in space and configuration; 3) the best density for transplant was 40 cm 40 cm with 5 cm 5 cm sward and main stalk (22.33 cm), leaf number (28.38), node number（24.76）and length of node segment（1.42 cm）were the highest; 4) with the increase of density, spacer length and branching intensity decreased, while the ramify angle increased.
