Abstract: Wild abortive cytoplasmic male sterile line Zhenshan 97A and its maintainer Zhenshan 97B were used as experimental materials, their yellowing seedling was treated soakedly by toxins from P. oryzae 902 strain. After the treatment, their homogenized suspension dynamic changements of oxidative activity were detected so as to understand specific inhibition of the toxins to respiratory system of WA cytoplasm. The result showed that the effect of toxins from P. oryzae 90 2 to respiration was different between Zhenshan 97A and Zhenshan 97B. The respiration of Zhenshan 97A was more susceptibility to the toxins and was inhibited greater than that of Zhenshan 97B. Moreover, the control respiratory intensity of Zhenshan 97B was always higher than Zhenshan 97A. This suggested that cytoplasmic character of Zhenshan 97B in respiration was better than that of Zhenshan 97A.
