模拟酸雨对水稻种子萌发及活力的影响

Influences on the germination and the vigor of seeds of rice through simulated acid rain

金华市酸雨污染严重 ,春冬两季酸雨频率高 ,p H较低 .用模拟酸雨处理早稻种子及幼苗 ,其萌发率和种子活力都明显下降 ,幼苗叶片受到明显伤害 ,并与模拟酸雨的 p H值成正相关 .

The acid rain pollution in Jinhua is serious. Acid rain, the pH of which is relatively low, appears frequently in winters and springs. Having treated the seeds and seedings of early rice with simulated acid rain, we found that the germination percentage and the vigor of seeds decended distinctly, the leaves of the seedings were wounded seriously,which is interrelated with the pH of acid rain.
