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 .
