Research carried out on mineral soil with mechanically damaged upper layer proved greater variability of general aspect between species than between varieties within a species. Among the investigated species, the following had higher general aspect values during the whole research period: Festuca ovina, Festuca rubra, and Lolium perenne; while Agrostis capillaris and Agrostis canina had lower values. Significant differentiation of the general aspect evaluations were observed only in Festuca genera variations, whereas evaluations of the general aspect of variations within the rest of the species were close. Sowing time did not significantly affect differentiation in the evaluation of the general aspect of varieties in Agrostis, Poa, and Lolium genera. However, spring sowing positively affected the general aspect of the Festuca ovina varieties and the Terros variety (F. anmdinacea).
