Gibberellin - as a determinant factor of grape’s quality of Codreanca (Black Magic) variety

Abstract

The vine area and volumes of production of table grapes in the country are not stable. In the last 15 years the vineyards decreased by 8 thousand ha (from 28 thousand to 20 thousand ha). The harvest and total production of grapes decreased too. The quality of grapes and the structure of assortment are unsatisfactory. The technological methods, which have a substantial contribution to improving the quality of table grapes, represents: foliar fertilizer use; removal cauliflowers; growth regulators use, which are used little or not use in the vineyards. Growth regulator use in the vineyards is used to improve the appearance of the grapes, increasing the productivity of plants and improve their taste. The purposes of investigations include the identification of the influence of the treatment period, the optimal dose of gibberellin on the quantity and quality of grapes and efficiency of table grapes of Codreanca (Black Magic) variety
