Tropospheric ozone levels are elevated throughout the northern hemisphere. The potential threat of ozone to vegetation urges for studying plant protection methods. The chemical ethylenediurea (EDU) is the most extensively utilized substance for protecting plants against ozone damage in research projects. This commentary provides collective evidence showing hormetic responses of plants to EDU and suggests that EDU may act as a conditioning agent against elevated ozone exposures. This article also suggests testing different substances in a hormetic framework for protecting plants against ozone damage. The concept of hormesis provides a significant perspective for reducing the economic cost for plant protection.
北半球对流层臭氧水平普遍升高。臭氧对植被的潜在威胁促使人们研究植物保护方法。在研究项目中，化学物质乙二脲（EDU）是用于保护植物免受臭氧损害的最广泛使用的物质。本评论提供了植物对EDU产生 hormetic 反应的综合证据，并表明EDU可能作为一种调节因子来应对升高的臭氧暴露。本文还建议在hormetic框架内测试不同物质以保护植物免受臭氧损害。hormesis概念为降低植物保护的经济成本提供了重要视角。
