| 摘 要： | 试验研究钐-甘氨酸-维生素B_6(Sm-Gly-VB_6)对模拟酸雨伤害大豆幼苗的防护作用结果表明,在pH2.5酸雨胁迫下大豆幼苗叶绿素含量减少,叶绿素a/b值下降,细胞质膜透性增加,过氧化氢酶(CAT)活性下降。而同一强度酸雨胁迫下经50mg/kg Sm-Gly-VB_6预处理的大豆幼苗叶片叶绿素含量、细胞质膜透性与过氧化氢酶活性损伤较轻,对酸雨伤害大豆幼苗有一定缓解效应。

| Abstract: | The protective effect of Sm-Gly-VB6 on the harm of soybean seedlings by acid rain was studied through vermic-ulite cultivation experiment. The results show that under acid rain (pH2.5) stress, the chlorophyll content and the chlorophyll a/b ratio reduce; the cell membrane permeability increases and the activity levels of catalase (CAT) decrease. However, under the same acid rain stress, in the soybean seedlings sprayed with 50 mg/kg Sm-Gly-VB6 , the harmfulness of chlorophyll content, the cell membrane permeability, and the catalase (CAT) activity are reduced. Therefore, Sm-Gly-VB6 can reduce the harmful effect of acid rain on soybean seedlings. |
