Abstract
All rose cultivars are propagated by asexual methods and the one of them is hardwood cuttings rooting. The aim of the study was to verify the possibility of effective propagation of shrub and pillar roses of different origin by hardwood cuttings. The shoots were collected in autumn. The cuttings were prepared and planted in spring. The rooting were conducted in open field and greenhouse. There were used commercial rooting powders containing IBA or NAA: Ukorzeniacz ABaqua, Ukorzeniacz Baqua, Rhizopon AA 020 XX, Chryzotek beige 004 XX, Ukorzeniacz – korzonek D DS. Of the ten cultivars chosen for the present experiment, only two took root effectively, with good quality rooted cuttings: ‘Excelsa’ (31.2% in open field, 56.5% in greenhouse) and ‘New Dawn’ (18.7% in open field, 14.3% in greenhouse). Using commercial rooting stimulants did not guarantee an increase in the number or in the parameters of growth of the rooted cuttings. The most ef-fective preparation was Chryzotek beige 004 XX for ‘Poppius’ (38.0%) rooted in the open field, and for ‘Kew Rambler’ (23.5%) in the greenhouse.
