[Architectural plasticity of the stoloniferous herb, Duchesnea indica in response to different elevation].
Architectural plasticity of clonal plant may modify its ways of utilization of resources through clonal growth and be of ecologically importance. The plasticity of clonal architecture in response to ecological conditions at different altitudes in a stoloniferous herb, Duchesnea indica, was investigated in an experiment with different elevations of 400, 800, 1200, and 1600 m. The results showed that the change patterns of spacer length, ramet density, branching intensity, and branching angle of Duchesnea indica were in a quadratic curve when the elevation increased. The architectural plasticity of D. indica was simulated through dynamic Logistic model, and the imitative effect was statistically preferable. Combining with the resources utilization of Duchesnea indica under different environments, the architectural plasticity was also discussed in this paper.
