Replication Data for: Time of the day of difference between leaf and air temperature (dT) and maximun stomatal conductance (gs_max) define the most appropriate reflects water status for potatoes

In the present study a potted trial, with the aim to relate maximum stomatal conductance (gs_max, an important water status indicator) with difference between leaf and air temperature (dT). Were compared gs_max and dT along the day in well-irrigated (field capacity) and water restricted (half field capacity) plants. An acute stomatal closure sensitivity was detected which drove a gs_max near the solar noon. The intense stomatal closure caused a dT rise which showed positive higher values (> 2 °C) after gs_max.

本研究开展了一项盆栽试验，旨在探究最大气孔导度（gs_max，一种重要的水分状况指标）与叶温-气温差（dT）之间的关系。研究比较了充分灌溉（田间持水量）和水分限制（半田间持水量）植株在一天中的gs_max与dT变化。结果发现植株具有敏锐的气孔关闭敏感性，导致gs_max在正午前后达到峰值；剧烈的气孔关闭引发dT升高，在gs_max出现后其值达到大于2°C的正高值。
