The aim of the work was the determination of the effect of the bed salinisation and alkalisation on germination and seedlings development of 8 basic turfgrasses. Bed was light soil, rate of salinisation was based on electrolitical conductivity (<4 mS cm⁻¹, 4-8 mS cm⁻¹, > 16 mS cm⁻¹) and ash from „Siekierki" Heating Plant. The results shows, that salinisation at the level 4-8 mS cm⁻¹ did not cause evident disturhances in germination of cultivars Nimba and Leo Festuca rubra, Nigra and Nira Lolium perenne and Igeka Agrostis capillaris. salinisation over 8 mS cm⁻¹ only cultivar Nimba Festuca rubra. The process of germination was effccted at lower degree of ash alkalinity than its salinisation. Alkaline pH significantly effected plant growth, especially roots.
