| Abstract:
Growth and cropping of 4-year-old cherry trees of 16 cultivars grafted on two rootstocks (Mazzard seedlings and F 12/1) were evaluated. Rootstocks did not affect tree growth with the exception of 'Stella', which showed significantly weaker growth on Mazzard seedling rootstock than on F 12/1. Among the cultivars studied, 'Burlat', 'Hedelfinger' and 'Heidegger' trees grew larger than 'Buttner's Red', 'Stella' and 'Spansche Knorpelkirsche'. Four-year-old trees of 'Ulster', 'Vega' and 'New York 980–1' gave the highest yield. The local Polish cultivar, 'Gubinska', and foreign cultivars 'Spansche Knorpelkirsche', 'Heidegger' and 'Lambert', produced the lowest crop. Rootstock had little influence on yield, with the exception of 'Mermat' and 'New York 980–1', which produced higher yield on Mazzard seedling than on F 12/1. Trees of 'Ulster' and 'Vega' demonstrated the highest productivity indices. The largest fruits among semi-early ripening cultivars were recorded on 'Vega' and 'Ulster', among late-ripening cultivars on 'New York 980–1' and 'Stella', and among very late-ripening cultivars on 'Lambert'. Rootstock had no influence on fruit weight. | |
