Nowadays, the debate involving climate change concerns safeguarding the water resources of the planet, an extremely important topic also in agriculture. In particular, the problem of scarce water availability becomes more and more pressing every year and at the agronomic level it is necessary to make intelligent use of water without affecting the quality and quantity of production. The aim of this work is to understand when the plant is under water stress conditions at the electrical signal level, in order to achieve the information of true needs of water in plants. The proposed methodology considered the plant black kale cultivated in hydroponic condition: the plants were based in an electrically isolated environment, with electrodes inserted in their stems to acquire and study the electrical activity associated with determined irrigation cycles. By using different stop/flow water irrigation regimes, an acclimated and a not-acclimated group of plants have been selected to experience different periods of prolonged water flow stress. Results indicated that the evaluation of a measure of statistical dispersion, the daily variance of the electrical resistance, can be closely related to the induced water stop/flow stress. Moreover, experiencing an acclimation stage has shown to allow a better recovery response for the plant.

如今，涉及气候变化的辩论涉及保护地球的水资源，这也是农业中极为重要的话题。尤其是，每年水资源短缺的问题变得越来越紧迫，在农艺水平上，有必要在不影响生产质量和数量的前提下明智地利用水。这项工作的目的是了解电信号水平下植物何时处于水分胁迫条件下，以便获得植物中水的真实需求的信息。拟议的方法论考虑了在水培条件下种植的植物黑羽衣甘蓝：这些植物以电隔离的环境为基础，在其茎中插入电极以获取和研究与确定的灌溉周期相关的电活动。通过使用不同的停/流水灌溉制度，已选择了适应环境的植物和未适应环境的植物，以经历不同时期的延长水流胁迫。结果表明，对统计分散性的度量（电阻的日变化）的评估可能与引起的止水/流动应力密切相关。而且，经历适应阶段已显示出对植物更好的恢复响应。
