The effect on transpiration in tomato on different tiers (Crisis tiers) was studied, which consisted of increasing transpiration parameters in option 1 (Standard) and option 2 (Load). The influence of regulated photosynthetic flow on the studied tomato under different conditions was studied. Changes in transpiration parameters (from 1.4*10-5 mol m-2 s-1 to 1.3*10-3 mol m-2 s-1) are reflected in the graphs. The portable LI-COR LI- 6800 system successfully measured several parameters in the same area of the leaf: photosynthesis (µmol m-2 s-1), transpiration (mol m-2 s-1), stomatal conductance (mol m-2 s -1). The average level of transpiration in the studied tomato on crisis tiers is different and is, in option 1 (Standard): 1.6 *10-4 mol m-2 s-1± 1*10-5 mol m-2 s-1, in option 2 (Load): 3.1 *10-4 mol m-2 s-1 ± 2*10-5 mol m-2 s-1. The average level of transpiration of the studied tomato on the control layer, in option 1 (standard) is 2.2 * 10-4 mol m-2 s-1 ± 3 * 10-6 mol m-2 s-1, in option 2 (Load) is 3.6 *10-4 mol m-2 s-1 ± 4 *10-6 mol m-2 s-1.
