BuskienëSummaryAfter two years of pruning the influence of pruning methods of four blackcurrant(R. nigrum L.) cultivars on growth vigour, productivity and berry mass were studied atthe Lithuanian Institute of Horticulture in 2004-2005. Different pruning methodsinduced blackcurrant shoot growth, except cv. Öjebyn. Depending on the pruningmethods their growth was by 40-70% more vigour than without pruning. Titania andÖjebyn grew less twice branches after second year of pruning. First year after the pruningyield of blackcurrant decreased, because bushes became younger. After the pruning of15-20 cm above the soil, yield of bushes reached 16-50%, above the soil – 13-40% ofcontrol (without pruning). The average berry weight after the pruning increased by30%.Key words: berry weight, blackcurrant, growth, yield, pruning methods.38
