The paper summarized the effects of acid rain on the morphology and structure of plants, the physiology and biochemistry of plants, the stress physiology from the level of individuals. Acid rain has the effect on the organelles of leaves, erodes the mesophyll tissues and destroys the structures of flowers ; Acid rain has no obvious effect on the rate of emergence, but inhibits on the pace of emergence to some extent ; And acid rain has effect on the photosynthesis and the nitrogen metabolism of plants; Acid rain leaching makes the precipitation of nutrient elements in plants, furthermore cause...
