Influence of growth regulator Asfac Bco-4® in Chasselas Doré variety

Abstract

The quality of table grapes is the result of combining superior physical properties (firmness, structure, weight) and the chemical composition and their functional properties, such as their main products of metabolism (sugars and organic acids) and secondary metabolites represented mainly by phenolic and aromatic compounds, and the ratio in which they are found in the fruit. Growth biostimulators are substances, which applied in small quantities and at the optimum time, increase grape production due to berry elongation, increase the sugar content of grapes and help in maintaining a good aspect. In countries with a tradition in producing table grapes, treatments with stimulators are often used due to a higher production and commercial aspect of the treated grapes. The application of treatment with ASFAC BCO-4® resulted in a larger production (6.825 kg compared to 5.67 kg). The commercial production percentage has also been improved (83% versus 75% in the variant without biostimulator treatments). An increased production per hectare was also observed (4.3 tons).
