for this variants the increases of transpiration rate and sub-stomatalcavity CO2concentration were noted (Table 2).Analyzing the results obtained at 30 days after sowing (Table 3)general improvement of pigment assimilation content was notedin the presence of tested solutions. The highest stimulatory effecton pigment assimilation by plants was measured in the presenceof DDW + SB (Chl a concentration was with 68.84% higher than forcontrol, Chl b content increases with 133.38% and carotene con-tent is higher with 116.57% compared with control).
