镉毒害对小麦生理生态效应的研究进展

镉是植物生长的非必须元素，它具有很大的生物毒性，与其它重金属相比，更易被植物吸收积累，即使生长在非污染土壤上的小麦，籽粒中镉含量都在0.002~0.207 mg/kg。在参考大量文献资料的基础上，综述了镉（Cd）毒害对小麦植株幼苗的萌发、生长及小麦生理生化特性的反应，提出了小麦镉毒害影响因素与防治途径。

Progress in Studies on Cadmium Toxicity to Psysiology and Ecology Effect of Wheat

Cadmium is not essential element to plant growth and its biotic toxicity is great.Cadmium is easily absorbed and accumulated by plant compared with any other heavy metals.Even if wheat which grown in non-polluted soil the concentration of Cadmium in its seeds is 0.002～0.207 mg/kg.The effect of Cadmium toxicity to sprouting and growth of wheat seeds,and to physiological and biochemical characteristics of wheat are summmarized.At the same time,effect factors and precaution about wheat Cadmium toxicity are suggested based on plentiful literature.
