CO2 concentration 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 for control, Chl b content increases with 133.38% and carotene content is higher with 116.57% compared with control).
