Changes in Yield and Quality Characteristics of Some Early Ripening Table Grape Cultivars (V-vinifera L.) in Response to Different Doses of Distinct Biostimulant Treatments

Abstract

Grape growers may occasionally face difficulties in grape skin coloration and low total soluble solids content in growing of early ripening table grape cultivars. In order to overcome these difficulties, it can be utilized from foliar biostimulants treatments. The purpose of this study, carried out 2015 growing season in Tekirda, Turkey, was to compare the effects of doses of two different biostimulants, enhancing table grape quality characteristics of cv. Tarsus Beyaz, cv. Trakya Ilkeren and cv. Yalova Incisi. For this aim, it was focused on three different doses for both biostimulants, including 0, 1750 and 3500ppm (respectively, Control, BStA-1 and BStA-2) for first biostimulant and 0, 3500 and 4500ppm (respectively, Control, BStB-1 and BStB-2) for second biostimulant. As aresult, present research demonstrated that BStB-2 and BStA-2 treatments especially enhanced most of table grape quality characteristics in cv. Tarsus Beyaz, cv. Trakya Ilkeren and cv. Yalova Incisi.
