| 摘 要： | 本文研究了钙对酸雨伤害甜瓜幼苗的影响。30mmol/L CaCl2处理甜瓜幼苗2次，可明显减轻pH2.5酸雨对甜瓜幼苗的酸致损伤。实验结果显示，此与钙能提高甜瓜幼苗光合速率、叶绿素含量，增加CAT活性与叶片Ca2+含量，减少MDA含量，降低质膜透性，维持细胞汁pH值稳定性等多重生理生态效应有关。

| Abstract: | The protective effect of calcium on muskmelon seedling harmed by acid rain was studied. When muskmelon seedlings were sprayed with 30 mmol/L CaCl 2 two times(once every 24h),the damage to muskmelon seedlings by acid rain at pH2 5 were reduced. The protective effect was because that CaCl 2 raised photosynthetic rate, chlorophyll content and Ca 2 content, increased catalase activity, decreased malondialdehyde content, reduced cell membrane permeability and kept stability of cell juice pH value of muskmelon seedlings, etc . |
