| 摘 要： | 为探究褪黑素对干旱胁迫下大豆抗坏血酸–谷胱甘肽（AsA-GSH）循环的影响,以大豆品种绥农26为材料,采用盆栽称重法,设置3个处理,分别为正常供水（CK）、干旱胁迫（D）和干旱胁迫喷施褪黑素（D+M）。结果表明,与CK处理相比,D处理大豆叶片的超氧阴离子（O2-.）和过氧化氢（H2O2）含量显著提高,D+M处理相比D处理在干旱后15d时,O2-.和H2O2含量分别显著下降了18.09%和17.37%。在干旱胁迫后10d时,D+M处理相比D处理AsA和GSH含量分别显著提高了22.39%和15.30%。相比D处理,D+M处理单株粒重显著提高了9.20%。综上所述,外源褪黑素可以提高干旱胁迫下AsA-GSH循环的效率,缓解干旱胁迫对大豆造成的氧化损伤。

| Abstract: | In order to investigate the effect of melatonin on soybean AsA-GSH cycle under drought stress, the soybean variety Suinong 26 was used as material, and three treatments were set up by pot weighing method: normal water supply (CK), drought stress (D) and drought stress with spraying melatonin (D+M). The results showed that the contents of O2-. and H2O2 in soybean leaves under D treatment were significantly increased compared with CK treatment, and the contents of O2-. and H2O2 on the 15th day after drought under D+M treatment were significantly decreased by 18.09% and 17.37%, respectively. On the 10th day after drought, the contents of AsA and GSH in D+M treatment were significantly increased by 22.39% and 15.30% compared with D treatment, respectively. The grain weight per plant of D+M treatment was significantly higher than that of D treatment, and 9.20% higher than that of D treatment. In conclusion, exogenous melatonin could improve the efficiency of AsA-GSH cycle under drought stress and alleviate the oxidative damage of soybean under drought stress. |
