The behaviour of ESR signal I in blue-green algae and chloroplasts is considered under various illumination and with various previous treatment. It is shown that the main process determining the kinetics of P700 plus reduction is the reaction with reduced components of the electron transfer chain between the two photosystems. If the accumulation of the products is inhibited by any way, then the reduction rate depends on the reactions with reducing agents in the incubation medium accumulated under irradiation before experiment. These exogenic reducing agents may be removed from the chloroplasts with repeated washings, and from algae-by means of the dark incubation for a long time. The relation of cyclic and noncyclic electron transfer is considered with and without artificial cyclic flow mediator.
在不同光照条件下以及经过不同预处理后，对蓝藻和叶绿体中ESR信号I的行为进行了研究。结果表明，决定P700⁺还原动力学的主要过程是与两个光系统之间电子传递链的还原成分发生反应。如果以任何方式抑制产物的积累，那么还原速率取决于与实验前辐照下在孵育介质中积累的还原剂的反应。这些外源还原剂可以通过反复洗涤从叶绿体中去除，而对于藻类，则可以通过长时间的暗孵育来去除。在有和没有人工循环流介质的情况下，考虑了循环和非循环电子传递的关系。
