摘要：Investigation of the effect of Magnaporthe oryzae on rice to breed resistant varieties is important to environment protection to reduce the use of chemical pesticides.Investigation of the effects of M.oryzae conidia on the photosynthesis and photosynthetic pigment contents of rice which plantlets were watered were conducted.The results showed that photosynthesis of rice was inhibited by stomatal and non-stomatal factors in rice which treated by M.oryzae conidia.The different rice responded to various M.oryzae physiological races were found to be statistically different.The Pn, E, Gs, Ci and chl a/chl b of the rice restoring line R725 were decreased significantly by ZA5 and ZA17.The Pn, E, Gs, chl a/chl b and Car content of the rice restoring line R720 were decreased significantly by ZC8 and ZF2.The ZF2 also can change significantly the Pn, E, Gs, chl a/chl b and Car content of the rice restoring line R727.
