Yield and physiology data of four African crops exposed to varying ozone concentrations, grown in solardomes, UK, 2017

Data are presented from an ozone exposure experiment performed on five African crops. The crops (Beans, cowpea, finger millet, pearl millet and wheat) were exposed to three different levels of ozone in the UK CEH Bangor solardomes. Wheat was grown at UK ambient temperature, whereas the solardomes were heated for the other crops to better mimic tropical conditions. The experiment ran from May 2017 to September 2017. The crop plants were grown from seed in pots in solardomes. The aim of the experiment was to investigate the impact of ozone exposure on the crop yield and plant health. The dataset comprises of manually collected data on plant physiology, biomass and yield. In addition the automatically logged data of ozone concentration and meteorological variables in the solardomes are presented. Plant physiology data is stomatal conductance of individual leaves, measured on an ad-hoc basis. The dataset includes the associated data measured by the equipment (relative humidity, leaf temperature, photosynthetically active radiation). Soil moisture of the pots was always measured at the same time, and chlorophyll content of the measured leaf was usually, but not always, determined at the same time. Yield was determined for each plant, in addition to yield-related metrics including mass per bean and 100 grain weight. For finger millet and pearl millet yield is expressed as weight of seed heads and number of seed heads, rather than explicitly as seed weight. The ozone and meteorological dataset is complete, but with some gap-filling for short periods when the computer was not logging data.
The work was carried out as part of the NERC funded SUNRISE project (NE/R000131/1). Full details about this dataset can be found at https://doi.org/10.5285/f38beff1-993f-4785-8a97-1de21e3e19c0

本数据集源于一项针对非洲五种作物（豆类、豇豆、 finger millet、珍珠米和小麦）的臭氧暴露实验。这些作物在英国CEH Bangor太阳穹顶中暴露于三种不同的臭氧浓度水平。小麦在英美环境温度下生长，而太阳穹顶则对其他作物进行加热，以更好地模拟热带条件。实验于2017年5月至2017年9月期间进行。作物植物在太阳穹顶内的盆中从种子开始生长。实验的目的是研究臭氧暴露对作物产量和植物健康的影响。数据集包括关于植物生理学、生物量和产量的手动收集数据。此外，还展示了太阳穹顶中臭氧浓度和气象变量的自动记录数据。植物生理学数据为单个叶片的气孔导度，以临时为基础进行测量。数据集还包括由设备测量的相关数据（相对湿度、叶片温度、光合有效辐射）。盆中土壤水分始终在同一时间进行测量，而测量叶片的叶绿素含量通常但并非总是与土壤水分测量同时进行。对每株植物的产量进行了确定，包括与产量相关的指标，如每豆质量和100粒重量。对于 finger millet 和珍珠米，产量以种子头重量和种子头数量表示，而非以种子重量明确表示。臭氧和气象数据集完整无缺，但在计算机未记录数据的一些短暂期间进行了数据插补。该研究作为NERC资助的SUNRISE项目（NE/R000131/1）的一部分进行。关于此数据集的详细信息可在https://doi.org/10.5285/f38beff1-993f-4785-8a97-1de21e3e19c0找到。
