Abstract :
The impacts of salicylic acid and silicon on some physiological parameters of maize seedlings in the presence of
cadmium (100 ?M) were investigated. Inhibitory effects of cadmium on seedling growth resulted in reduced shoot
and root fresh weight, low percentage of relative water content, low chlorophyll, free proline and soluble sugars
contents and a low rate of lipid peroxidation. Results indicated that salicylic acid and silicon alleviate the
inhibitory effects of cadmium on maize seedlings by increasing both their chlorophyll content and fresh weight.
Although individual treatments of salicylic acid and silicon reduced plants free proline, soluble sugars and
cadmium uptake and lipid peroxidation rate, they improved root and shoot fresh weights in both cadmium stressed
and unstressed seedlings. When combined, salicylic acid and silicon alleviated the inhibitory effects of cadmium
on seedlings significantly.
