Effect of La on corn seedling growth under Cd stress

Hydroponic culture experiment was conducted to study the effect of La on corn seedling growth under Cd stress. The results show inhibition of corn seedling growth by Cd stress.The height, root length,leaf area,shoot and root fresh weight and dry weight decrease remarkably under Cd stress. With increased Cd²⁺ concentration, damage to corn plant becomes serious. Application of 20mg/L La during the growing stage of corn seedling markedly alleviates Cd stress damage.
