Visible leaf injury of Trifolium repens versus Lolium perenne after ozone exposure in solardomes

The dataset consists of proportions of ozone injured or senesced leaves from a study which investigated how the presence of competing species in a community affects these two common responses to ozone. Monocultures and mixtures of Trifolium repens and Lolium perenne were grown in large containers and were exposed in solardomes to either a rural episodic ozone profile (AOT40 (Accumulated Ozone Threshold exposure of 40 parts per billion) of 12.86 ppm h) or control conditions (AOT40 of 0.02 ppm h) for 12 weeks. The proportion of ozone-injured or senesced leaves was determined in different regions of the canopy, the upper canopy (>14cm high), the canopy edge and the inner canopy, by separating injured/senesced leaves from healthy leaves. The experiment was carried out at the CEH Bangor Air Pollution Facility.

本数据集包含来自一项研究的数据，该研究探讨了群落中竞争物种的存在如何影响臭氧导致的叶片损伤或衰老两种常见反应的比例。在大型容器中种植了三叶草（Trifolium repens）和羊茅（Lolium perenne）的单种和混合种植，并在太阳能温室中暴露于乡村突发性臭氧浓度（AOT40，即臭氧积累阈暴露量40 ppb的12.86 ppm h）或对照条件（AOT40为0.02 ppm h）下，持续12周。通过将损伤/衰老叶片与健康叶片分离，在树冠的不同区域（上层树冠（>14cm高）、树冠边缘和内层树冠）确定了臭氧损伤或衰老叶片的比例。该实验在CEH Bangor大气污染设施进行。本研究由生态与水文中心整合基金倡议资助。关于本数据集的详细信息可在以下链接找到：https://doi.org/10.5285/bc4d0325-b67b-4fff-a14b-6e06edf397bd。
