【Abstract】 The content of chlorophyll and the permeability of cell membrane of wheat were analyzed through research on the effect of man made simulated acidic rain on the photosynthetic speed of wheat Wanmai 19. The result indicated that the sensibility of physiology characteristic of wheat to acidic rain was decided by acidic rain’s pH. pH value 4 was the key point to affect physiology characteristic of wheat, and as pH value was reducing, the effect was increasing. Effect of acidic rain on wheat would cause the wheat premature.更多还原
