Abstract:

Cadmium (Cd) is one of the most serious soil pollutants in China. It can accumulate in plants through absorption by roots or leaves, leading to interference in various physiological and biochemical functions, causing disruption of plant physiological metabolism and growth inhibition. Calcium (Ca) plays an important role in the growth and development of plants and the response to environmental signals. The effects of exogenous Ca on the Cd accumulation and distribution, growth and development, photosynthesis, antioxidant system, nutrients and morphological indicators of the plants were summaried, and the mechanism of Ca signaling induced plant response to Cd stress was discussed, which provided reference for plant ecological remediation of Cd-contaminated soil.

Key words: calcium, cadmium, physiology and biochemistry, response mechanism

摘要:

镉是中国最严重的土壤污染物之一,可以通过根系吸收或叶面吸收而在植物体内积累,进而影响植物各种生理生化功能,引起生理代谢紊乱和生长受阻。钙在植物的生长发育及其对环境信号的响应中起重要作用。综述了外源钙对植物体内镉的积累与分布、生长发育、光合作用、抗氧化系统、营养物质、形态指标等的影响,并阐述了钙信号诱导植物应答镉胁迫的作用机制,以期为植物生态修复镉污染土壤提供参考。
