Abstract: Compared between two analysis methods of the photosynthetic light-response curve data,the non-rectangular hyperbola model was found to be more objective to calculate the photosynthetic parameters and simulate the photosynthetic light-response curve when the data were processed by the nonlinear statistical regression function of SPSS software and combined with linear regression in the low light period. Binomial regression curve could simulate photosynthetic light-response curve data,but it could not calculate apparent quantum yield(φ) and explain that net photosynthetic rates (Pn) predicted declines quickly when photosynthetic photo flux density(PPFD)excesses the light-saturation point.
