Abstract—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.
Index Terms—Tillering stage, Magnaporthe oryzae, photosynthesis, photosynthetic pigment.
