Abstract

Abstract: To study the physiological influence on depurative plants in different pollution pressures and physiological differences between different plants, TN, TP, GSA and NRA of roots and stems of 4 kinds depurative wetland plants were compared in two kinds of nitrogen and phosphorus conditions - the WRSIS wetland and Etou Pool. The result showed that: (1) The TN, TP of wetland plants had no significant difference between the two conditions. For nitrogen and phosphorus absorption, stems were more effective than root. (2) Higher nitrogen and phosphorus condition could enhance GSA in plants and GSA was generally higher in stem than in root. The plant with better depurative efficiency had higher GSA. (3) There was no significant influence on NRS in higher ammonium condition. The difference of NRS in different parts of plants was insignificant. Therefore, pollution pressure had no significant influence on TN and TP of plants, and TN, GSA were positive correlated with depurative efficiency.
