Abstract: With leaves of 1-year-old -Phyllostachys pubescens seedlings under water deficiency to different extents, changes in photosynthetic parameters were studied using a gas exchange photosynthesis system, MiniPam chlorophyll fluorometer and fluorescence imaging in order to understand the effects of water deficiency stress on photosynthetic and chlorophyll fluorescent characteristics and water use efficiency. Results showed that: 1) with an increase of water deficiency stress, decrease in activity of the photosystem II (PSII) central reaction was consistent with the decreasing photosynthetic rate, which mainly resulted from stomatic limitation and inactivation or damage to PSII central reaction reversibility; 2) from non-stress (NS) to heavy stress (HS), light saturation points（LSP）, the maximum net photosynthetic rate, Fv/Fm and effective quantum yield decreased by 20.45%, 67.22%, 22.46% and 45.60%, respectively; 3) water use efficiency (WUE) increased by 17.81% under light stress than under NS, while photochemical quenching coefficient (qP) and nonphotochemical quenching coefficient (qN)decreased first, followed by an increase then; and 4) variation coefficients of Fo, Fm and Fv/Fm increased with the increased water deficiency stress, the values of which ranged from 18.182% to 26.404%, from 16.321% to 24.899% and from 1.291% to 33.932%, respectively.
