Changes in the intensity of leaf transpiration in an apple tree depending on the time of day in Uzbekistan

In this article, we studied the amount of water consumed and the daytime time needed to grow apple trees, transpiration and release into the atmosphere by leaves and other tree organs. Thus, the transpiration index shows that a lot of water consumes the plant for the construction of each unit of dry substance mass. The intensity of transpiration varies greatly during the daytime. With an increase in temperature and a decrease in the relative humidity of air, the intensity of transpiration increases, step by step, from the morning hours to the daytime hours.
