Abstract
The wheat samples were sprayed during its vegetative and productive stages by simulated acid rain of northern China,whose pH values were 2.0,3.0,4.0,5.0 and 6.0 respectively.The results show that the visible blade injures threshold value is pH3.0 after the treatment of acid rain.The mean leaf area is suppressed evidently.The water content of wheat is not sensitive to acid rain in the range of 71.4% to 85.0%.The chlorophyll content reduces in the range of 0.4% to 37.1%,while the malondialdehyde content increases in the range of 4.5% to 49.3%.The catalase activity declines in the range of 9.7% to(94.4%,) while the peroxidase activity increases in the range of 40.1% to 54.7% at the first stage and is suppressed in the range of 8.6% to 33.1% at the end of the treatment.Effects of simulated acid rain on wheat increases more and more remarkable with the increase of hydrogen ion concentration,which is correlated with disposal times and doses.
