How can we measure transpiration
WebThe rate of transpiration in a plant varies depending on a range of conditions, including light intensity, relative humidity, wind speeds and temperature, as well as between plant species. Various manipulations to the plant can also affect transpiration rate. In this practical, students use a potometer to measure the rate of transpiration. Web19 de ago. de 2024 · That is transpiration. Combine the two and that's evapotranspiration – the process through which water leaves plants, soils and other surfaces. It’s a measurement that farmers can use to estimate the amount of water being taken up or used by their fields and crops.
