Abstract: A pot experiment was conducted to study the biomass allocation and morphological characteristics of Dichondra repens under different levels of shading (100%, 66%, 205%, and 9% transparency). With the increase of shading, the biomass per plant decreased after an initial increase, being the maximum under 66% transparency. The biomass allocation per plant also varied with increasing shading. Leaf mass ratio and petiole mass ratio increased while root mass ratio decreased, and stem mass ratio increased first and decreased then. The branching angle decreased with increasing shading, and the stem length, branching intensity, leaf area, and petiole length decreased after an initial increase. D. repens had definite adaptability to varied light environment. Moderate shading benefited the growth and development of D. repens, i.e., increased the modular numbers and biomass accumulation, while high light intensity or high shading did harms to D. repens growth.
