摘要: 运用4种光合作用光响应模型对3种十大功劳属植物的光响应数据进行拟合,提取了各光响应模型的主要特征参数并对比分析了各模型参数间的差异。结果表明:不同模型对同一种十大功劳的光响应曲线的拟合结果存在着差异;同一模型对不同十大功劳的光响应曲线的拟合效果也不同;但直角双曲线修正模型对3种十大功劳光响应曲线的拟合效果最佳。因此,在研究植物的光响应时,应考虑光响应模型对植物的整体拟合效果,不能以某个参数作为衡量标准来选取最优的光响应模型。

关键词: 光响应曲线模型, 十大功劳, 模型拟合

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
