Influence of limiting factors on the physiologicale processes of plants of the genus Solanum
Abstract
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.
