摘要 光响应曲线研究方法被广泛应用在植物生理的研究中,但是在应用光响应模型拟合光响应数据时,往往只考虑到研究的目的,很少考虑到模型是否适用于所研究的植物。本文通过采用7个不同的光响应模型对白桦叶片和兴安落叶松针叶光响应曲线数据拟合的比较,发现不同模型对同一种植物光响应曲线的拟合结果存在着差异,同一模型对同种植物不同部位叶片光响应曲线的拟合效果也不同,所以在研究植物的光响应时,应考虑到所选光响应模型对该种植物的光响应情况的描述是否恰当。根据具体情况选择最佳模型,以最大限度地保证估测生理指标结果的精确性。 Light responsive curve models have been widely used in plant physiological studies. However, most of the researchers emphasize their study aims, ignoring the practicability of the used models to their special plant materials. In this paper, 7 different light responsive curve models were compared to investigate the fitted effects using bireh(Betula platyphylla Suk. ) and larch (Larix gemelinii (Rupr.)Rupr. ). The fitted results using the different models for the same species were different. Furthermore, the fitted results using the same model for the leaves of different parts of the same species were different also. These results indicated that it is necessary to consider the practicability when a model is used to a selected plant species and the optimal model is essential to ensure the accuracy of the estimated physiological parameters.
