It is a common opinion that main challenge for plant production is to cope with environmental stresses, both abiotic and biotic. Although biostimulator Asahi SL has been used for years to improve plant status and obtain possibly the highest and best quality yield, especially under conditions unfavourable for plant cultivation, its mode of action is still not understood. In this work the effect of Asahi SL on Arabidopsis thaliana plants grown under drought stress was studied. Plants grown under drought stress conditions and treated with Asahi SL were, as compared to untreated, higher and more advanced in development, particularly generative. Biomass accumulation was stimulated by biostimulator mainly due to better photosynthetic apparatus efficiency manifested by a higher (i) assimilation area, (ii) chlorophyll content, (iii) intensity of photosynthesis and (iv) improvement of chlorophyll a fluorescence parameters. Asahi SL treated plants were characterized by a lower concentration of biological active ABA. Despite the higher transpiration and lowered stomatal resistance RWC and water content were unchanged in Asahi SL treated plants which can be explained by increased water uptake in biostimulator sprayed plants. The obtained results clearly showed that the application of biostimulator played a protective role against drought stress.

Asahi SL stimulates plant’s vital processes like growth and development, affects physiology and biochemistry, what often leads to increased biomass accumulation and yield. However, common is opinion that application of this preparation could be beneficial only, when treated plants are grown under unfavorable conditions. Therefore the aim of this work was the assessment of the stimulatory effect of Asahi SL on Arabidopsis thaliana L. and ornamental amaranth plants grown under optimal conditions. Plants treated with Asahi SL were higher and more advanced in development, particularly generative. Biomass accumulation was greater after biostimulator application mainly due to better photosynthetic apparatus efficiency, which was manifested by (i) greater leaf area, (ii) higher total chlorophyll content and (iii) increased intensity of photosynthesis. Effect of Asahi SL on chlorophyll a fluorescence was marginal. Despite of higher transpiration and lowered stomatal resistance the RWC was almost unchanged in biostimulator treated plants what was attributed to increased water uptake. Obtained results clearly showed that Asahi SL applied on plants can also be effective and beneficial when they are grown under optimal conditions.

The effect of CaCl2 and NaCl with anti-corrosion additives (ammonium phosphate 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, performance 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.
