How do we measure transpiration
WebThe transpiration rate is measured in ml/min or cm/min. Using a potometer, we could estimate the transpiration rate in two ways: Indirect Method: Here, we need to measure the reduction in the volume of water in the capillary tube over some time. Direct Method: Here, we need to measure the loss in mass of the potometer over some time.
