干旱胁迫下3种玉米光响应曲线模型的比较
Fitting Light Response Curve of Photosynthesis of Maize Under Drought Stress
摘要
Abstract
The purpose of this study was to select the best model of photosynthetic light response of maize ear-leaf under different soil moisture conditions by fitting three different models-rectangular hyperbola model, non-rectangular hyperbola model and modified model of rectangular hyperbola. The results showed that the parameters fitted by the rectangular hyperbola model were all higher than those fitted by the non-rectangular hyperbola model in CK, the AQY and Pnmax 33% higher, the LCP 10% higher, the Rd 40%higher. The Pnmax fitted by the modified model of rectangular hyperbola was lower than that fitted by the non-rectangular hyperbola model, other parameters were almost the same. The MS fitted by the three models were also almost the same with CK. Modified model of rectangular hyperbola could calculate these photosynthetic parameters and the fitting results accorded with measurements under normal water supply condition and drought stress.关键词
