presents the same trend of evolution as that observed at 30 days, but the value registered at 60 days evidences a higher stimulatory effect. All tested solutions induce an increasing content of assimilatory pigments. The highest stimulatory effects on chlorophyll a, b and carotene pigments were registered in case of plants treated with DDW + SB (40.48%,130.97%, 150.34%) and spruce bark extract – SB1 (Table 3).
