Abstract: To understand the effect of different phosphorus (P) on leaves photosynthesis in Phyllostachys violascens,P treatments of 0,0.5,5.0,50.0 and 500.0 mgL-1;chlorophyll fluorescence parameters;and photosynthetic active radiation-electron transport rate (PAR-ETR) response curves of one-year old Phyllostachys violascens were studied through a sand-pot experiment. Results showed that as P increased and potential photoreception activity (Fo /Fm) decreased,the maximal photochemical efficiency (Fv /Fm) dropped (P<0.05) in the range of 0 - 50.0 mgL-1 P. The chlorophyll fluorescence basal rate (Fo),maximum chlorophyll fluorescence (Fm),timely minimum fluorescence (Ft) and variable fluorescence (Fv) were highest (P<0.05) with 5.0 mgL-1 P. In addition,ETR and the actual photochemical rate of PSⅡ (Yield) were higher,but photochemical dissipation (qP),non-photochemical dissipation (qN),and non-photochemical quenching (NPQ) coefficients were lower (P<0.05) with 5.0 mgL-1 P. Higher or lower P concentration than 5.0 mgL-1 caused ETR to decrease,heat dissipation to increase,the photochemical effect to decrease,and quantum yield to decrease. Accordingly,the biological yield of Phyllostachys violascens decreased,and the Apase activity increased. Therefore,P concentration of 5.0 mgL-1 was appropriate for growth of Phyllostachys violascens in a sand-pot incubation.[Ch,1 fig. 3 tab. 20 ref.]
