Study on Photosynthesis Models of Oriental Lily ‘Siberia’

The model of light temperature CO2 and Pn was established by taking net photosynthetic rate as objective function to speculate the optimum temperature and the active radiation of photosynthesis of Oriental lily 'Siberia'.The results showed that the regression model had much higher precision and less errors(R2=0.9)and the predicted result was accorded with the experiment data basically.Oriental Lily 'Siberia' of photosynthesis under different CO2 concentrations in the optimal temperature and optimal photosynthetic active radiation was no significant difference in photosynthesis,the optimum temperature of photosynthesi for Oriental lily 'Siberia' was approximately 22 ℃,and the optimum photosynthetically active radiation of photosynthesis for Oriental lily 'Siberia' was approximately 1452 μmolm-2s-1.
