外源水杨酸、脱落酸、黄腐植酸、脯氨酸对植物抗旱性比较研究
Exogenous Salicylic Acid, Abscisic Acid, Xanthohumic Acid, Proline Comparative Study on Drought Resistance of Plants

本文以外源水杨酸、脱落酸、黄腐植酸、脯氨酸为研究对象，探讨了这些物质对植物抗旱性的比较研究。通过分析它们的作用机制和调节植物生理响应的能力，我们评估了它们在增强植物抗旱能力方面的效果，并比较了它们在单独应用和混合使用时的差异。研究结果表明，外源水杨酸、脱落酸、黄腐植酸、脯氨酸都能显著提高植物的抗旱性，但其作用机制和效果存在差异。同时，通过不同比例的混合应用，我们发现某些物质之间存在协同效应，能够进一步提升植物的抗旱能力。本研究对于理解这些物质在植物抗旱机制中的作用，为制定有效的抗旱策略提供了重要的理论依据。
In this paper, the effects of exogenous salicylic acid, abscisic acid, xanthohumic acid and proline on drought resistance of plants were studied. By analyzing their mechanisms of action and ability to regulate plant physiological responses, we assessed their effectiveness in enhancing plant drought resilience and compared their differences when applied alone and when used in combination. The results showed that exogenous salicylic acid, abscisic acid, xanthohumic acid and proline could significantly improve the drought resistance of plants, but their mechanisms and effects were different. At the same time, through the mixed application of different proportions, we found that there is a synergistic effect between certain substances, which can further improve the drought resistance of plants. This study provides an important theoretical basis for understanding the role of these substances in drought resistance mechanism of plants and for formulating effective drought resistance strategies.
