The present research covered 13 commercially available mixes of lawn grass seeds (3 Polish and 10 imported). Seed material was X-rayed by means of X-ray apparatus „Elektronika-25" with standard exposure parameters. Percentage contribution of healthy seeds, damaged or empty seeds and seeds effected by fungi diseases was established on the basis of visual analysis of X-ray seed images. Moreover, seed establishment in the year of sowing and sward density in the second year of utilisation was evaluated. The studies showed that both Polish and imported lawn grass seed mixes varied in the percentage contribution of healthy, damaged, empty seeds and seeds infected with fungi. The highest functional value (70,4-87,8% of healthy seeds) was found in 4 mixes only. The lowest amount of healthy seeds was noted in two English mixes (16,7% and 35,5%) and two Danish mixes (30,4 and 42,4% ). Quality of the sowing material influenced plant establishment in the year of sowing and sward density in the following year.
