Abstract
The aim of the study was to determine the variability of traits of lawn varieties of grasses applied for recreational lawns. The study was conducted in 2010–2013 at the Collection of Cultivated Plants in SGGW. The objects of the research were lawns varieties of Kentucky bluegrass, red fescue and perennial ryegrass. Aesthetic aspect, cover, leaf fineness and colour, presence of weeds, resistance of diseases and roots density were evaluated. There were also determined the regrowth intensity of plants and synthetic evaluation index of variety. Observations were performed in 9° scale, three terms in each year: spring (May), summer (July) and autumn (September). Sward utilized extensively. It were found clear differences in most of tested traits. Perennial ryegrass distinguished by clearly better general aesthetic aspect and the most aligned cover compared to other varieties. Red fescue had the best of leaf fineness with dark green colour. Simultaneously, they were characterized by the weakest cover. Both of Kentucky bluegrass varieties showed the slow rate of regrowth. All tested varieties obtained good density of the root system. The study was demonstrated the diversity of value of the synthetic index in species and varieties of lawn grasses. The relationship between the general aesthetic aspect and cover of evaluated varieties was highly associated with the weather conditions, especially precipitation.
