| 摘 要： | 为完善延迟荧光检测植物光合能力的方法,通过对4种样品延迟荧光光响应曲线分析,提出四段式光响应曲线模型.从理论上推导出非饱和延迟荧光强度与光合能力具有线性转换关系,且线性系数与饱和光诱导下的线性系数有关.以水稻(Jing Dao No.21)为样本,对理论分析结果进行实验验证.结果表明,两者具有较强的线性关系,验证了理论推导的正确性.理论和实验分析均证实,非饱和光诱导延迟荧光可以作为表征植物光合能力的一种有效手段.

| Abstract: | A 4-curve light response model was proposed after analyzing delayed fluorescence(DF) light response curves of four different samples to improve the DF detection capabilities for plant photosynthetic ability.The linear correlation between unsaturated DF strength and photosynthetic ability was deducted in theory,and the linear coefficient is related to that of saturated light-induced.The leaves of rice(Jing Dao No.21) were choosen as the samples to demonstrate the linear correlation,and results show that ther... |
