Abstract	The effect of CaCl2 and NaCl with anti-corrosion additives (ammonium phos- phate and sodium hypochlorite in amount of 3 to 5% of preparation weight), protected by Polish patent no. 198058, applied in concentrations of 4, 8 and 12 g dm -3 on germination and seedling vigour of Lolium perenne L. cv. Solen and Festuca rubra L. cv. Nimba was evaluated. Other studied parameters were: chlorophyll content, chlophyll a fluorescence and biomass accumulation in Canna × generalis, Rosa rugosa L. and Lolium perenne L. under the influence of the above mentioned substances. It was found that application of de-icing substances delayed and reduced germination of grass seedlings and declined root growth. Red fescue was less tolerant for increased salinity in soil than perennial ryegrass. Application of de-icing substances on rugosa rose, canna lilly and perennial ryegrass plants led to decrease of chlorophyll content, potential photochemical efficiency, per- formance index and biomass accumulation. Without anticorrosion agents the least toxic was calcium chloride and the most sodium chloride. Additives to de-icing road salts, in general, decreased NaCl toxicity and increased toxicity of CaCl2.
