Abstract

Green operations are vital in improving the quantity and the quality of the vine product. The range of the green operations is large; yet, the topping of shoots and the special treatment of the side-shoots remain two of the most important interventions whose impact on the product indicators is undeniable. These operations aim to balance the vegetative growth and the bunch productivity, by redirecting part of the organic substance of the shoots to the bunch growth. It has been observed that these interventions influenced the pollination potential, which resulted in an increase of the grape grains in the bunch. There is a relation between the time and the frequency of the light topping of the shoots whose impact on the vine activity is great. Various intensive toppings of the shoots bring different results in different ecological contexts and cultivars. Heavy late toppings, especially in cold regions Korçë, have negative impact, since the action extends the vegetation period and prevents proper maturity of the shoots. These interventions become more delicate when it comes to cultivars with middle or long-term ripening period, like the Black Serin cultivar (vitis vinifera). The current study aims to instruct vinedressers about the proper time and frequency of the topping of this cultivar, in order to create a possible vegetation and production equilibrium, as well as qualitative ripeness of the grape.
