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. This work was funded by the Centre for Ecology & Hydrology Integrating Fund Initiative

本数据集包含来自一项研究的数据，该研究旨在探讨群落中竞争物种的存在如何影响叶片对臭氧的两种常见反应（臭氧损伤或衰老）。该研究在大型容器中培育了三叶草（Trifolium repens）和黑麦草（Lolium perenne）的单种和混合种植，并将其置于太阳穹窿中进行暴露处理，暴露于乡村偶发臭氧轮廓（AOT40为12.86 ppm h）或对照条件（AOT40为0.02 ppm h）达12周。通过将损伤/衰老叶片与健康叶片分离，在冠层的不同区域（如冠层上部（>14cm高度）、冠层边缘和冠层内部）确定了臭氧损伤或衰老叶片的比例。实验在CEH Bangor大气污染设施进行。该研究由生态与水文中心整合基金倡议资助。
