Abstract: In this study, genet, mother ramet and some clonal fragments of Potentilla anserina were used to analyze the effect of partial shading. The quantitative traits and biomass allocation of root, stem and leaf were also measured. The purpose of the study was to analyze the effect of partial shading on the morphological plasticity and biomass allocation of the mother ramet, daughter ramet and genet of P. anserina. The results showed that: 1) For mother ramets, partial shading displayed a significant effect on plant height, leaf length, leaf width, leaf area and root depth (P<0.05). Partial shading increased plant height, leaf length and total leaf area, but different shading positions or shading intensities had different effects on leaf width, single leaf area and root length. 2) For daughter ramets, partial shading had a significant impact on leaf length and leaf area. Shading of the clonal fragment was the main factor affecting leaf size of daughter ramets, with shading of mother ramets second placed. 3) Partial shading significantly increased the number of cloned fragment daughter ramets and new daughter ramets, and also increased the cloned fragment number of genets (P<0.05). Shading mother ramets had an important influence on stolon elongation and the formation of new cloned fragments. 4) Partial shading displayed a highly significant effect on the root, stem and leaf water content of genets, as well as on their leaf and root biomass accumulation (P<0.01). With shading of more than 2 clonal fragments or mother ramets, the root biomass accumulation of genets significantly increased, but with full shading of genets the root biomass was clearly lower than the control. 5) Partial shading also had significant effects on the allocation ratio of stem, leaf and root biomass of genets (P<0.01). Shading had the greatest effect on leaf allocation ratio and a lower effect on stem allocation ratio, but the lowest effect was on the root allocation ratio. 6) Partial shading had a significant effect on the underground biomass ratio (P<0.01). Shading had an important effect on the root/stem and stem/leaf ratios (P<0.01), which increased remarkably with full shading. In summary, partial shading displayed a direct influence on the morphological plasticity and biomass allocation of various types of P. anserina plants, including mother ramets, daughter ramets, clonal fragments and genets.
