水稻暴露于 p H 2. 5～ 4. 2的模拟酸雨中 2个月后测定表明: 叶片叶绿素含量下降 ,细胞液离子外渗率增加 ,气孔阻抗增高 ,蒸腾速率降低。 不同叶位的水稻叶片对模拟酸雨的敏感性不同 ,杂交稻 (汕优 63)对模拟酸雨的敏感性较粳稻 (中粳 864)高。
 

Rice was exposed to p H 2. 5～ 4. 2 simulated acid rain for two months, the chlorophyll content and transpiration rate of leaves were reduced, with the percent of percolating ion and stomatal resistance increasing. The leaves in different leaf position possessed different sensitivity to simulated acid rain. Hybrid rice ( Shanyou 63) was more sensitive than keng rice ( Zhongjing 864) to simulated acid rain.
