Abstract: To reveal the response of Phyllostachys pubescens to climate change,an Li-6400 was used to measure CO2 response curves and light response curves under different temperatures,humidity,and CO2 concentrations. The data above was used to simulate climate change in a short time with SPSS. Results showed that photosynthesis doubled as did the light saturation point,the transpiration rate decreased,and the CO2 response curve fit a quadratic function where the CO2 concentration doubled from 400 to 800 molmol-1 in a short time. Temperatures above or below external temperature 3 ℃ caused a net photosynthetic rate increase with stomatal conductance surge increasing sharply. Also,the transpiration rate continuously increased with temperature. As stomatal conductance increased,the net photosynthetic rate increased slightly. When humidity decreased suddenly the transpiration rate had a seven-fold increase. Therefore,thefertilization effectcould lead to an increase in the net photosynthetic rate with the CO2 concentration increasing in the short-term;however,the greenhouse effect and possible drought caused by an increase in CO2 concentration could make stomatal sensitivity and the quantity of Rubisco activity limiting factors,even limited the whole plants normal physiology and growth.[Ch,4 fig. 3 tab. 21 ref.]
