| 摘 要： | 在中度盐害的情况下,用含氨基酸的过渡金属(Cu、Mn)SOD模拟物对玉米浸种、叶面喷施,八叶期后对幼苗的生理生化指标进行检测,结果发现经SOD模拟物浸种、叶面喷洒处理,生物量提高1.32%～15.77%(鲜重)和7.05%～15.89%(干重),光合速率提高17.60%～41.40%,叶绿素含量提高7.20%～26.51%,体内SOD活性提高最高达38.75%。初步表明上述SOD模拟物能有效抑制玉米幼苗所受的盐害胁迫作用。 |

| Abstract: | The effect of the SOD mimics containing transition metals and L-amino acids on salt stress of maize seedlings was investigated. The seeds of maize were treated with a certain concentrations of SOD mimics (0.1-0.5mol L-1) by the way of soaking and spraying. The biomass,chlorophyll content,photosynthetic rates and SOD activities were determined in the-8th-ledf period. The results showed that SOD mimics could increase biomass(1.32%-15.77%,7.05%-15.89%) and chlorophyll contents(7.20%-26.51%),improvd photosynthetic rates(17.60%-41.40%) and enhancd the high SOD activities(0%-38.75%),whieh means that the SOD mimics could protect the maize seedling against the salt stress. |
