Data for the paper: X-ray micro-CT imaging to study foliar water uptake mechanisms in plants with contrasting leaf topography

µCT data collected at the DANMAX beamline of MAX IV. Data shows how hydraulic activation of stomata can be achieved using a controlled system with high humidity and low CO2 content. Waterfilms containing iohexole for contrast were applied to barley and potato leaves at varying surface tensions and then scanned at times ranging from 30 min to 14 hours after application. All plants are scanned in a custom build sample holder keeping the plants in a controlled atmosphere and exposed to as little radiation as possible. 3D video visualizations of most interesting datasets are included. Raw projection data is available as h5 files in the folder Raw.<b>Version history:</b><br>Version 1 – Only reconstructed data<br>Version 2 – Updated title and included raw projection data<br><br>

本数据集为在MAX IV实验室DANMAX光束线采集的显微CT（µCT）数据。本数据集展示了如何通过高湿度、低二氧化碳含量的可控系统实现气孔的水力激活。将添加了作为造影剂的碘海醇（iohexole）的水膜以不同表面张力施加于大麦与马铃薯叶片，并在施加后的30分钟至14小时的不同时间点进行扫描。所有植株均置于定制样品架中完成扫描，该样品架可维持植株处于可控大气环境，并尽可能减少辐射暴露。本数据集包含多数最具研究价值的数据集的三维视频可视化结果。原始投影数据以h5文件格式存储于Raw文件夹内。<b>版本历史：</b><br>版本1：仅包含重建后数据<br>版本2：更新了数据集标题，并新增原始投影数据<br><br>
