Optimization of Pruning in High-stem Cultivation of Cabernet Sauvignon Grapevine Variety
Year: 2024
Type: article
Abstract: The influence of the length of the fruiting canes on the productive capacity of the Cabernet Sauvignon grapevine variety grown on the Umbrella formation in the soil and climatic conditions of southern Bulgaria was studied. The percentage of developed blind buds and fruiting shoots on knots and fruiting canes was found to be highest in variants with pruning for 6 winter eyes and longer with 9 winter eyes, while the trend was reversed for winter eyes allocated above blind bud. The winter eye fertility rate has been shown to be highest in the variant with the longest fruiting canes with 12 winter eyes. The values of this indicator for blind eyes of the fruiting canes decrease slightly with increasing length, while for winter eyes the decreasing order by variant is reversed. The yield per vine and per acre and the mass per bunch were shown to be highest in the variant with pruning of 10 knots of 2 winter eyes and 4 fruiting canes of 9 winter eyes, which under the soil and climatic conditions of the experiment should be preferred.
