Abstract
With the pH value of acid rain declining, the activities of superoxide dismutase(SOD) and ascorbate peroxidase(AsA-POD), the contents of glutathione(GSH) and ascorbic acid(AsA) in the chloroplasts of longan leaves decreased while the malondialdedyde(MDA) content increased. SOD and AsA-POD activities, GSH and AsA contents increased when the leaves were treated with acid rain of pH 3.0 for the first two hours, then reduced gradually with time. It was accompanied by the increase of MDA content. The thylakoid membrane collapsed and grana lamelle mixed up when treated with pH 3.5.Injury effect of acid rain of pH 3.0 on granaa lamelle aggravated. Fig 5, Plate 2, Ref 21
