Exogenous Spermidine

The absorption characteristics of copper and the effect of spermidine on the absorption of copper ions were investigated in Salix Matsudana in a short-term hydroponic experiment. There different concentrations of copper ions with or without the addition of spermidine in nutrition solution were conducted in this experiment. The effect of spermidine on the adsorption by S. Matsudana was also studied. 5, 10, 20 mg/L were chosen as the copper stress concentration. Absorption time and the initial copper concentration influence the absorption process in S. Matsudana. The absorption rates increased very fast at the first hours then increased slightly and attained an asymptotic value. After 72 h, the removal rates of Cu were 75.00%, 61.47% and 43.60% with the initial copper concentrations of 5, 10, 20 mg/L, respectively. The addition of spermidine influenced the absorption process of Cu by S. Matsudana. In 72 h, the treatment with spermidine increased the copper removal by S. Matsudana than the only copper treatment. Results indicated that exogenous spermidine could improve the absorption of copper in S. Matsudana and was beneficial to phytoremediation in heavy metal contaminated environment.
