Abstract:
Based on a hydroponic experiment, the effect of the simulated acid rain(pH2.0 and pH3.5)was investigated on the nitrate reductase activities of leaves in Acorus gramineus and Saururus chinensis. The main results were described as follows:(1)There existed extremely significant impact on the leaf nitrate reductase activity for both aquatic plants caused by eutrophication treatment(three levels); with the increase of eutrophication level the leaf nitrate reductase activity increased first and then decreased afterwards.(2)There was no significant impact on the leaf nitrate reductase activity for both aquatic plants caused by the simulated acid rain(pH2.0 and pH3.5). With the increase of acid rain concentration level. The leaf nitrate reductase activity represented a decreasing trend; the leaf nitrate reductase activity of Acorus gramineus and Saururus chinensis reduced with increase of acid rain processing times.
