Dimitar Vasilev, Svetoslav Malchev
Abstract: The study was conducted in the period 2018 – 2019, in the nursery garden of Khan Krum Agricultural Research Centre, Shumen region. The experiment is based on the block method of control with four repetitions. The nursery is maintained under
irrigated field conditions and the application of traditional agricultural techniques. The subject of the study are eight flat peach cultivars: Mesembrine, Poragnayo ricla, Sicilian local, Flat queen, Flat late peach, ASF – 2 – 80, Flat light, UFO 4, as well as some from the group of dessert peach cultivars – Red Haven (for standard). The studied varieties were cultivated on seed rootstock (Elbert) and clonal rootstock GF 677. The cultivation was performed in August, on a dormant bud, using the method of T-shaped cut of the stock. We analyzed the following indicators – autumn and spring budding percentage, growth rate patterns and thickening of the stem. The budding percentage in the autumn reporting varies from 81.7 to 96.2%, and the spring budding percentage is in the range of 78.2 – 94.1%. ASF-2-80 cultivar, showed the greatest growth rate. It was cultivated on GF 677, rootstock and it reached a height of 182.2 cm and a stem thickness of 18.1 mm.
