中文摘要:
      用盐水、淡水处理耐盐番茄和对照番茄(未导入外源DNA),对其生长情况和各种生理生化指标进行分析,结果表明:盐协迫下耐盐番茄植株生长良好,而对照番茄生长受到抑制,植株矮小;盐协迫下耐盐番茄叶片维生素C、脯氨酸、叶绿素、可溶性糖含量明显高于对照的,蛋白含量下降的幅度比对照的大,MDA浓度比对照的低, SOD活性比对照番茄稍有下降。因此,耐盐番茄具有较强的耐盐性。
英文摘要:
      Salt solution and fresh water were used to irrigate the salt tolerant and control tomatoes. The control tomatoes were not introduced with exogenous DNA. The results showed that the salt tolerant tomato plants grew better than the control when they were irrigated under salt stress, and the control tomato plants grew short. Additionally, the salt tolerant tomatoes were obviously higher in the leaf content of vitamin C, proline, chlorophyll and soluble sugar than the control, but much higher in the leaf protein content and lower in the leaf MDA content than the control. Their leaf SOD activity declined slightly than that of the control. It was suggested that the salt tolerant tomato had a high salt resistance.
