Początkowy wzrost i rozwój wybranych gazonowych odmian Lolium perenne w różnych warunkach siedliskowych

The study presents the assessment of initial growth and development of three Lolium perenne L. varieties (Natara, Nira and Taya) in two research series, in two habitats: A – in Sosnowica, at the Didactic-Research Station of the Department of Grassland and Landscape Forming, University of Life Sciences in Lublin and B – on the embankment of National Road No. 17 alongside the Piaski-Łopiennik stretch. In laboratory conditions, thousand grain weight (TGW) and grain germination capacity (in %) were assessed, while in field conditions the seedling growth and root elongation rate (mm) were assessed on the 20th, 40th and 60th day from the sowing date. The responses of the studied varieties to soil conditions were different. Regardless of the research series, the fastest seedling growth rate on mineral soil (habitat A) was observed for the Nira variety while on anthropogenic soil with an undeveloped profile (habitat B) – for the Natara variety. Regardless of the soil and weather conditions in both research series, the highest seedlings and longest roots were found in the Nira variety.
