These results show that there may be two different processes of photodamaging to photosystem I reaction center and P680 is most sensitive to light treatment.

所有这些结果表明，光破坏至少存在两个不同的过程，而且主要受到破坏的是原初电子供体P680。

This finding seems to be an indirect experimental evidence supporting our hypothesis proposed for understanding the directionality of electron transfer within reaction center of photosynthesis.

这一发现可视作为对我们所提出的解释光合作用反应中心的电子转移方向性的设想提供一个间接实验支持。

With the research of chlorophyll fluorescence parameters may reflect the energy utilization in photosynthetic reaction center and changes of biological activity when the plants under drought stress.

结合叶绿素荧光参数的研究，可以反映出当植物受到干旱胁迫时，光合反应中心的能量利用情况和生物活性的变化。
