Abstract: With the copper pollution aggravating in the environment, the problems of copper physiological toxicity to higher plants become increasingly serious. The paper reviews the recent studies on copper physiological toxicity to higher plants at home and abroad, especially discusses the effects of the excess copper on photosynthesis, cell structure, cell division, enzymology system and the absorption of the other nutrition of higher plants. At the same time, the paper points out the existing problems and the prospects of the studies.
