Abstract
Photosynthesis was affected considerably when the cultivars Zenith, Lacrosse, Usen and Co. 13 belonging to indica and japonica groups of rice were inoculated with physiological races IC13 and ID1 ofPyricularia oryzae Cav. The 21-day seedlings after inoculation withP. oryzae and uninoculated control were exposed to14CO2 under natural sunlight (190 Wm-2). The extent of reduction in photosynthetic rate in the cultivars varied on inoculation with different races ofP. oryzae used, the reduction being more apparent with race ID1.
