摘　　要：近年来,烟草的重金属安全性引起了人们的广泛关注,也一直是国内外烟草研究的热点之一。烟草属于易富集镉的作物,土壤镉污染已成为影响我国烟叶品质安全的重要因素。镉不仅抑制烟草的生长发育、影响烟叶品质,还对烟草吸食者的健康构成潜在的威胁。作者综述了镉胁迫对烟草生长发育、生理特性及烟叶品质的影响,探讨了烟草对镉毒害的抗性机理,并对烟草镉防治相关研究进行了展望。In recent years, the heavy metal in tobacco leaves has caused increasing public concern and been both domestic andinternational research focus on tobacco. Tobacco could readily uptake cadmium from soils. The cadmium accumulation by tobacco inpolluted soils is becoming one of the most important factors which affect the tobacco quality and security. The cadmium stress insoils could not only affect the physiological process and reduce the quality of tobacco, but also it is harmful to smokers. In this paper,the growth, physiological characteristics and quality performances of tobacco with the cadmium uptake are reviewed, and thecadmium resistance mechanism is discussed and some integrated approaches to reduce the uptake of cadmium by tobacco aresuggested for further research.
