摘　　要：为了探讨酸雨对小麦种子萌发的影响,以商麦5226为材料,模拟p H值为2.0、2.5、3.0、4.0、5.0五种酸雨,研究其对小麦萌发过程中种子的发芽率、发芽势、发芽指数、活力指数以及幼苗体内SOD、POD活性、MDA含量7个指标的影响。结果表明,随着酸度的增加,小麦的发芽率、发芽势、发芽指数、活力指数和SOD活性整体呈下降趋势,而POD活性和MDA含量呈增加趋势。不同p H值的酸雨对小麦种子萌发有着不同程度的影响。In order to study the effect of acid-rain stress on seedling of germination of wheat, taking Shangmai 5226 as tested material, 7 indexes, namely germination rate, germination energy, germination index, SOD activity, POD activity and MDA content, were measured during germination of wheat in its leaves under 5 different acid-rain levels（2.0、2.5、3.0、4.0、5.0）. The results showed that germination rate,germination energy, germination index and SOD activity decreased as the acidity increased, while the POD activity and MDA content showed opposite trend. Acid rain of different p H values has an effect on germination of wheat at different levels.
