Abstract:Because plants cannot move, they must be able to tolerate environmental variation, which provides a plausible explanation of why woody plants exhibit so great phenotypic plasticity in canopy growth. The growth of woody plants is a process of the accumulation of modules, and hence knowledge of module dynamics is essential to our understanding of the mechanisms of plant canopy plasticity. Larix chinensis is distributed in the alpine regions (altitude 2600~3600m) of Qingling Mountain in Shannxi Province, China...
