【Objective】The chlorophyll contents and light response curves of Phyllostachys edulis were studied to compare analysis on the response characteristics of water stress and discuss drought resistance physiology and adaptation,so as to provide the theoretical basis for water management in this species.【Method】The experiment was conducted with one-tofive-year-old Ph. edulis plants. The photosynthetic pigment contents and light response curves were recorded,and photosynthetic parameters,including the maximum net...
