摘 要:Cadmium(Cd),a life threatening hazardous heavy metal is abundant in *** amounts are greater in leaves than other plant parts,and it shows considerable effects on *** oxide(NO),a free radical present in living organisms,is now known as an important signaling molecule playing various physiological processes in *** this study,the possible ameliorative effect of NO on photosynthesis was examined on pea seedlings grown under Cd *** showed that chlorophyll,net photosynthetic rate,transpiration rate,stomatal conductance,photochemical efficiency of Photosystem II and Photosystem I decreased,and Fo and nonphotochemical parameters for PSII and PSI significantly increased due to Cd *** suggests that Cd affects the photochemistry efficiency at both the PSII and PSI *** oxide supplementation through SNP ameliorated Cd stress by enhancing all the above mentioned parameters but causing a reduction in the Fo,and non-photochemical parameters of PSII and PSI in pea *** data indicate that the exogenous application of NO was useful in mitigating Cd-induced damage to photosynthesis in pea seedling.
