Cadmium is a non-essential element for tobacco (Nicotiana tabacum cv.Xanthinc) growth, but easily absorbed.Cadmium ion can not only be remained in the tobacco, but has the obvious harm on its growth.The tobacco leaves are induced to produce callus by the minimal medium, MS+1.0 mg·L-1 6-BA+0.5 mg·L-1 NAA, introduced in this paper.After 45 days, with a large amount of callus, the activity of related enzymes in antioxidant system, the level of reactive oxygen species (ROS) and malondialdehyde (MDA) content in tobacco callus are measured every three days.
