Abstract: In this paper, four models of light-response curves of photosynthesis were used to fit the light response data of three species of Mahonia, and the primary parameters and indices obtained by different models were compared. It was showed that the fitted results using different models for the same species and using the same model for different species were different. The main photosynthetic parameters calculated by the modified rectangular hyperbola model were in good agreement with the measured data of three species of Mahonia. Therefore, we should consider the whole fitted results rather than one amongst parameters as a standard to choose the most optimal light response model in the study of the light-response of the plants.

Key words: light response curve model, Mahonia, model fitting
