摘要: To ultimately determine whether different levels of soil nitrogen (N) deposition can modify the detrimental effects cadmium (Cd), seedlings Toxicodendron vernicifluum (Strokes) F. A. Barkley were exposed to Cd stress (0, 5 and 15 mg kg(-1) dry soil), N 13 40 soil) their combinations. Soil caused damage in plant growth, photosynthesis other physiological indexes, ultrastructure mesophyll cells. The on lipid peroxidation enzyme activities depended relative amounts supplied. combination low was positive activities, it lower accumulation compared with effect alone. high led a higher peroxidation, as T. found be sensitive stress. had seedlings, but tolerance increased under deposition.
