The respiration,photosynthetic activity and some physiological parameters were measured in wheat leaves under N,P or K deficiency for 10～30 days. Under macronutrient deficiency,H2O2、MDA increased,the water content decreased,and the cyanide resistant respiration was induced apparently. Net photosynthesis rate (Pn),ΦPSⅡ,Fv/Fm,Fv′/Fm′and nonphotochemistry quenching(NPQ) declined under N or P deficiency. K deficiency resulted in decline of NPQ,but its other photosynthetic parameters did not change significantly. All these results indicated that macronutrient deficiency had remarkable effects on plants,but individual mechanisms were different. Nitrogen deficiency hampered protein synthesis,phosphorus deficiency affected energy metabolism,potassium deficiency increased membrane penetration. The effects of K deficiency were relatively small. The possible mechanisms of regulation of photosynthesis and respiration under macronutient deficiency were discussed.
