摘要: 棉花是对重金属以及其它类型非生物逆境耐性较强的作物。虽然重金属胁迫对棉花的生长发育造成不利影响,但因棉花自身具有较完整的应对重金属胁迫的适应保护机制、且棉花主产品非食用的特点,可作为重金属污染土壤的修复作物。本文结合本实验室的研究结果,就国内外对镉、铬、铅、砷和汞5种主要重金属污染物源对棉花生长发育的毒害机理以及棉花应对和适应机制的研究进展作了评述。

Abstract:  In China, the risk of cotton production on arable land contaminated with heavy metals has increased in recent years. Compared with other major crops, cotton shows stronger and widespread resistance to abiotic stresses such as heavy metals. As the main product of cotton is non-edible fibers, and cotton possesses a set of sophisticated stress-resistance strategies, cotton is an ideal crop for use in phytoremediation of soil contaminated by heavy metals. We present a global review of recent literature on the toxic effects of five heavy metals (cadmium, chromium, lead, arsenic, and mercury) at present in China and their effects on cotton, as well as summarize recent studies on the mechanisms of avoidance and avoidance both. We aim to provide insights into understanding the mechanisms of resistance to heavy metal stress in cottonunderstanding the relationship between cotton and heavy metal stress.

Key words: cotton; heavy metal stress; tolerance; study advances
