摘要: 土壤盐渍化问题日趋严重,充分开发利用盐渍化土壤对提高粮食产量具有重要作用。探究外源物质对盐胁迫下冬小麦的影响具有重要意义。本研究通过不同质量浓度硫酸锌浸种处理冬小麦种子,分析了盐胁迫下冬小麦萌发特性的变化。结果表明:在50 mmol/L和90 mmol/L NaCl胁迫下,0.2 g/L硫酸锌浸种处理均能显著提高冬小麦种子的发芽势、发芽指数、活力指数、幼苗鲜质量和干质量,且在50 mmol/L NaCl胁迫下的增幅高于90 mmol/L NaCl处理;同时,0.2 g/L硫酸锌浸种处理也能显著提高冬小麦的苗高和根长;0.6 g/L硫酸锌浸种处理则能显著提高种子的活力指数和幼苗鲜质量。综合分析表明,在低盐胁迫下,采用0.2 g/L硫酸锌浸种能有效提高冬小麦种子的萌发能力。

Abstract: Soil salinization is becoming more and more serious. Since it is important to make full use of salinized soil to increase grain production, it is of great significance to study the effects of exogenous substances on winter wheat under salt stress. The effects of different concentrations of zinc sulfate on the germination of winter wheat were studied under salt stress. The results showed that the germination potential, germination index, vigor index, seedling fresh weight and seedling dry weight of winter wheat seeds treated with 0.2 g/L zinc sulfate were significantly increased compared with the control under 50 mmol/L and 90 mmol/L NaCl. At 50 mmol/L NaCl, these indicators compared with the control showed a greater increase than at 90 mmol/L NaCl. The seedling height and root length of winter wheat were significantly increased treated with 0.2 g/L zinc sulfate too. The vitality index and seedling fresh weight of winter wheat were significantly increased treated with 0.6 g/L zinc sulfate. The suitable concentration of zinc sulfate for treating winter wheat seeds is 0.2 g/L under low salt stress. The germination ability of winter wheat could be effectively improved by treating seed with 0.2 g/L zinc sulfate under low salt stress.
