Kinetics of manganese uptake and accumulation in hyperaccumulator plant Phytolacca americana Linn
摘要
Abstract
The kinetics of manganese uptake and accumulation by the hyperaccumulator plant Phytolacca americana Linn, were investigated. The results show that concentrations of Mn in tissues (leaves, stems, roots) increase progressively with the increase of Mn concentrations. With a supply of 0.2, 0.5, and 5.0 mmol/L Mn2+ treatments, Mn content in tissues (leaves, stems, roots) fluctuates with time, reaches the maximum at 5 d, and then decreases slightly with growth time. In the first 48 h, manganese uptake by P. Americana is a quick process. However, there is a difference between high Mn2+ (5 mmol/L)and low Mn2+ (0.2 and 0.5 mmol/L) concentrations. The kinetics of manganese uptake and accumulation in the hyperaccumulator plant P. Americana are determined by Mn concentrations and growth time.关键词
