Salicylic acid belongs to a diverse group of plant phenolics. It is a natural signaling molecule involved in the regulation of different physiological and biochemical processes. The way in which exogemous salicylic acid acts depends on several factors, such as the plant species, the environmental conditions (light, temperature etc.) and the concentration of salicylic acid solutions. Tomatoes (Lycopersicum esculentum) are an important dietary source of micronutrients and antioxidants. The beneficial properties appear to be related to the lycopene and carotene content and the antioxidant content particularly ascorbic acid, polyphenols, total flavonoids, which may play a role in inhibiting reactions mediated by reactive oxygen species. In the present research the influence of exogenously applied salicylic acid on the content of some bioactive compounds was analyzed. Two different concentrations of salicylic acid solution (50 and 100 ppm) were applied on the leaves of two variety of cherry tomato (Idyll and Red Pear). The treatments were applied at 21, 30 and 45 days after the seedlings were planted. The results obtained indicated that 100 ppm concentration of SA was most effective in the foliar treatment in terms of content in bioactive compounds.
