THE EFFECT FROM BUNCH CUTTING AND SHORTENING ON ‘MUSCAT OF HAMBURG’ GRAPES CULTIVATED IN THE MOUNTAIN-VALLEY COASTAL REGION OF CRIMEA
The paper provides an overview of the impact of bunch cutting (bunch removal) and berry thinning-out (bunch shortening) at the stage of a pea on ‘Muscat of Hamburg’ cultivar cultivated in the mountain-valley coastal region of Crimea. It was established that upper cluster removal from the shoots significantly reduces the fructification and fruit-bearing capacity ratio values of the shoots. Leaving only the bottom bunches increases their weight by 10.7%, however, reducing the overall bush yield by 19.5 38.3 per cent. Bunch shortening by 1/3 of the length increases their weight by up to 20.3%, thus increasing the bush yield by 6.2-13.1%.
