WebTranspiration in plants refers to the natural process in which a plant releases excessive water into the atmosphere as water vapours like a human body does. A human releases its excessive water through sweating, whereas transpiration is the term used in the case of plants. Plants use nearly 5% of the water to fulfil their basic needs like food ... WebJun 6, 2024 · In arid and semiarid lands, canopy transpiration and its dynamics depend largely on stomatal sensitivity to drought. In this study, the sap flow of a dominant species, Haloxylon ammodendron growing in Central Asian deserts, was monitored using Granier-type sensors, from which the canopy stomatal conductance was derived. The responses …
