本文用一个新的植物叶片的光响应模型详细讨论了植物在低光强时光合速率与光强之间的关系。并用新的植物叶片的光响应模型重新拟合了丹参的光合响应数据。拟合结果显示新模型拟合的结果与实验测量值符合得很好。认为在自然条件下,在低光强时植物丹参的光合速率对光强的响应不是线性。
Relationship photosynthetic rate of plant leaf with irradiance for Salvia mihiorrhiza at low photon flux densities were discussed in detail by the model. The data of light-response of photosynthesis of Salvia mihiorrhiza were modeled again. Results were shown that photosynthetic rate to irradiance of Salvia mihiorrhiza at low photo flux densities was nonlinear response in natural condition.
