okres poczatkowy - Opis:
- This paper presents results of examinations carried out in 2006–2007 which aimed at performing initial differentiation of 11 Kentucky bluegrass (Poa pratensis L.) in respect of selected morphological traits and above-ground mass yield quantity. Measurements were carried out in the presence of two standard varieties, i.e. a lawn variety Alicia and a fodder form Skrzeszowicka. The examined population of smooth Kentucky blue-grass ecotypes proved to be relatively uniform in respect of most analysed morphological traits and green and dry matter yield quantity. Among them, object pod02 426 deserves special attention as being characterised by the best uniformity of analysed parameters and attaining higher values in relation to such traits as Lpw, Ll, Szbl and A as well as plant productivity, favourable for meadow use. Thousand seed weight did not significantly affect the value of most analysed traits, except green matter yield (r = – 0,714) and leaf blade mass (r = – 0,581). However, it was observed that forms developing longer vegetative shoots and leaf blades with larger assimilation area during 4 examination months were also characterised by higher yield of green and dry matter.
