As the supply of urban lawn grass‘ irrigation is expensive and laborious it is important to fi nd other methods which are eff ective against the water defi ciency. The aim of the study was therefore the assessment of hydrogels‘ infl uence on the the most common grass species (Festuca rubra, Festuca ovina, Lollium perenne) which were cultivated under controlled drought stress. Results indicated that this watersorbent increased the germination, growth and dry matter content of tested species. It was therefore concluded that using hydrogels on grasslands seems to be reasonable in accordance to the water defi ciency problems.

The investigations were conducted in the years 2002-2004 in the Floriculture Station in Skrzeszowice near Krakow (altitude of 220 m). In the experimental object designed by the split-splot method in four replicants, four grass species were taken juto account i.e.: Festuca pratensis cultivar Skawa, Festuca rubra cultivar Brudzyńska, Phleum pratense cultivar Skald and Poa pratensis cultivar Eska 46. Among all examined species, uninfected and infected with stalk rust (Puccinia graminis) plants were selected. The level of infection determined in a 9-degree scale amounted to 5°, 4°,6° and 2°, respectively. The aim of this work was to determine the infection influence on the macroelements' con-tent in selected grass species. Uninfected plants were characterised with the highest total protein content: from 8 % for Phleum pratense to 27 % for Poa pratensis, phosphorus: from 13 % (Phleum pratense) to 36 % (Festuca pratensis, Poa pratensis) and potasium: from 9 % (Festuca rubra) to 70 % (Poa pratensis) than infected plants. On the other hand, infected species were richer in calcium, magnesium and sodium by 34-48 %, 11-20 % and 19-148 %, respectively.

Badania przeprowadzono w latach 2002-2004 na terenie Stacji Hodowli Roślin w Skrzeszowicach pod Krakowem (220 m n.p.m.). W doświadczeniu za-łożonym metodą losowanych bloków w czterech powtórzeniach, uwzględniono cztery gatunki traw Festuca pratensis odmiana Skawa, Festuca rubra odmiana Brudzyńska, Phleum pratense odmiana Skald oraz Poa pratensis odmiana Eska 46. Spośród badanych gatunków wydzielono rośliny zdrowe i porażone przez rdzę źdźbłową (Puccinia graminis), przy czym stopień porażenia w skali 9 stopniowej wynosił odpowiednio 5°, 4°, 6° i 2°. Niniejsza praca miała na celu określenie wpływu porażenia na zawartość makroelementów u wybranych gatunków traw. Rośliny zdrowe charakteryzowały się większą zawartością azotu ogólnego od 8 % u Phleum pratense do 27 % u Poa pratensis, fosforu od 13 % (Phleum pratense) do 36 % (Festuca pratensis. Poa pratensis) i potasu od 9 % (Festuca rubra) do 70 % (Poa pratensis) niż rośliny porażone. Gatunki zainfekowane były bardziej zasobne w wapń o 34-85 %, magnez o 11-20 % oraz w sód o 19-148 %.

The objective of the research project was to determine the predisposition of Festuca rubra cultivars to deposit mat on lawns in their first year after establishment. In a field experiment of randomised blocks (blocks of 1 m2 in three replications) carried out in the Brody Experimental Station, twenty cultivars of Red Fescue fertilised with the following two levels of NPK fertilisation (kg/ha): I - 60 : 20 : 40 and II - 120 : 40 : 80 were investigated. In order to evaluate the over ground part of turf in its 0-5 cm layer, its weight was determined. Later, this plant material was used to perform chemical analyses with the aim to determine lignin and cellulose concentrations and to calculate the ratio of these two compounds (L/C). The obtained results allowed to conclude in the first year of utilisation, the examined cultivars of Festuca rubra exhibited considerable variability of the weight of turf over ground part and its Chemical composition with regard to lignin and cellulose. The highest L/C ratio indicating the tendency of Red Fescue to deposit plant mat faster was observed in Barcrown, Adio and Smirna cultivars. Intensive mineral fertilisation resulted in the inerease of lignin concentration and L/C ratio in the examined cultivars of Festuca rubra.
