This overview of experimentally induced effects of ozone aims to identify physiological and ecological principles, which can be used to classify the sensitivity to ozone of temperate grassland communities in Europe. The analysis of data from experiments with single plants, binary mixtures and multi-species communities illustrates the difficulties to relate individual responses to communities, and thus to identify grassland communities most at risk. Although there is increasing evidence that communities can be separated into broad classes of ozone sensitivity, the database from experiments under realistic conditions with representative systems is too small to draw firm conclusions. But it appears that risk assessments, based on results from individuals or immature mixtures exposed in chambers, are only applicable to intensively managed, productive grasslands, and that the risk of ozone damage for most of perennial grasslands with lower productivity tends to be less than previously expected.
本关于臭氧实验诱导效应的概述旨在确定生理和生态原理，这些原理可用于对欧洲温带草原群落对臭氧的敏感性进行分类。对单株植物、二元混合物和多物种群落实验数据的分析表明，将个体反应与群落联系起来存在困难，从而难以确定最易受影响的草原群落。尽管越来越多的证据表明群落可分为对臭氧敏感性的大致类别，但在现实条件下使用代表性系统进行实验的数据库太小，无法得出确凿结论。但似乎基于室内暴露的个体或未成熟混合物结果进行的风险评估仅适用于集约管理的高产草原，而对于大多数生产力较低的多年生草原，臭氧损害的风险往往低于先前预期。
