Tolerance and Heavy Metal Accumulation Characteristics of <i>Sasa argenteostriata</i> (Regel) E.G. Camus under Zinc Single Stress and Combined Lead–Zinc Stress
<i>Sasa argenteostriata</i> (Regel) E.G. Camus is a gramineous plant with the potential for phytoremediation. In this study, we aimed to determine its tolerance to zinc stress and combined lead–zinc stress and the effect of zinc on its absorption and accumulation characteristics of lead....

| description | <i>Sasa argenteostriata</i> (Regel) E.G. Camus is a gramineous plant with the potential for phytoremediation. In this study, we aimed to determine its tolerance to zinc stress and combined lead–zinc stress and the effect of zinc on its absorption and accumulation characteristics of lead. The results showed that <i>S. argenteostriata</i> had good tolerance to zinc stress, and <i>S. argenteostriata</i> was not significantly damaged when the zinc stress concentration was 600 mg/L. Under both zinc stress and combined lead–zinc stress, the root was the main organ that accumulated heavy metals in <i>S. argenteostriata</i>. The presence of zinc promoted the absorption of lead by the root of <i>S. argenteostriata</i>, and the lead content in the root under PZ1, PZ2, PZ3 and PZ4 treatments was 2.15, 4.31, 4.47 and 6.01 times that of PZ0 on the 20 days. In the combined lead–zinc stress treatments, the toxicity of heavy metals to <i>S. argenteostriata</i> was mainly caused by lead. Under high concentrations of combined lead–zinc stress (PZ4), the proportion of zinc in the leaf of <i>S. argenteostriata</i> on the 20 days increased, which was used as a tolerance strategy to alleviate the toxicity of lead. |
