抗氧化酶中，沙丘芦苇的SOD、CAT、POS和APx的活力均显著高于沼泽芦苇，显示出比沼泽芦苇更强的ROS清除能力。

The activities of SOD , CAT , POD and Apx were significantly higher in dune reed than in swamp reed under stress thus suggested that dune reed possessed stronger potential of eliminating ROS .

C4植物种占所测植物种的1/5左右，主要分布于固定沙丘上，且随着生境土壤湿度的增大其与C3植物种的光合速率差异逐渐缩小。
