Rezumat

To improve the quality of horticultural crops are used a series of biostimulants to accumulate the amount of sugar and increase the intensity of color. The study took a variety of table grapes with medium maturity, Muscat of Hamburg, in the conditions of Cluj Napoca. The vines were planted in the didactic collection of the Faculty of Horticulture, in the USAMV Cluj Napoca campus. The climatic conditions of 2020 (spring with low temperatures) determined the delay of the phenophases of vegetation by 3 weeks, including up to the phenophase of veraison and ripening of the grapes. In this case, the application of the Maturex biostimulant was done only once, on September 7, when the grapes were 5-10% in the veraison. The application was made by spraying, with an atomizer, in a concentration of 30 ml per 10 liters of water. The experience included the control variant (untreated) and the treated variant. The grapes were harvested for analysis 6 weeks after treatment, which consisted in determining the weight of the grape, the sugar and total acidity content in the berries, the mass of 100 berries, the mechanical analysis of the grape composition and the berries sphericity. According to the OIV codes, visually notes were awarded. The results showed signifficant differences between the treated version and the untreated version in terms of sugar content in the berries and unformity in skin color.
