植物生长和恢复力需要平衡固有的氧化代谢与强大的抗氧化系统，帮助维持体内平衡。当环境发生变化时，活性氧是这种变化的有力指标，可以通过重新平衡新陈代谢和抗氧化系统来适应。大量的证据支持使用外源抗氧化剂来改善植物生长及其对压力的适应能力。值得注意的是，一些表型效应在应用化学上不同的抗氧化剂时是相似的，而另一些是不同的。在这篇综述中，我们分析了抗氧化剂处理实验的研究，并强调了它们在实际应用中的相似之处，以及它们对植物抗逆性、光合作用、天然抗氧化系统和植物激素的影响。我们还简要介绍了单独应用的抗氧化剂的具体效果，以及它们的潜在作用模式。鉴于抗氧化剂应用的强大潜力，我们讨论了促进其农业用途所需的研究。最后，我们确定了突出的问题，如何外源应用抗氧化剂机械影响植物生长。
Plant growth and resilience require balancing an inherently oxidative metabolism with powerful antioxidant systems that help maintain homeostasis. When the environment changes, reactive oxygen species are potent indicators of that change, allowing adaptation through re-balancing metabolism and antioxidant systems. A large body of evidence supports the use of exogenously applied antioxidants to improve both plant growth and their resilience to stress. Notably, some phenotypic effects are similar upon the application of chemically diverse antioxidants, while others are distinct. In this review, we analyze research from antioxidant treatment experiments and highlight the similarities in their practical applications and their effects on plant stress tolerance, photosynthesis, native antioxidant systems, and phytohormones. We also briefly cover the specific effects of individually applied antioxidants and what is known about their potential modes of action. Given the strong potential of antioxidant applications, we discuss research needed to promote their agricultural use. Finally, we identify outstanding questions about how the exogenous application of antioxidants mechanistically affects plant growth.
