Effect of 2, 4, 5-T in different concentrations and time of herbicide applications on protein biosynthesis and enzymatic activity of proteases and acid phosphatases in needles of spruce seedlings was investigated. 2, 4, 5-T in all concentrations tested and applied on the seedlings during phase of intensive growth caused significant increase in soluble protein content. After spraying the seedlings with 100 and 300 mg ·l-1 of 2, 4, 5-T before bud development a small decrease in soluble protein level was noted. The herbicide caused marked disturbances in the activity of enzymatic systems of proteases and acid phosphatases. No effect of 2, 4, 5-T on dry matter accumulation was observed
