Effect of gibberellic acid concentration and number of treatments on yield components of “Einset Seedless” grapevine cultivar
Studies were conducted in the Faliszowice Vineyard (50°39'N; 21°34'E), Sandomierz Upland, Poland in 2011–2013. This research aimed to assess the influence of gibberellic acid (GA3) concentrations and number of applications on the table grape cultivar ‘Einset Seedless’. The objective was to evaluate the yield and quality after one, two, or three spray applications of GA3 (7, 14 and 21 days after full bloom) at 100, 200 and 300 mg/l. Unsprayed vines constituted the control. GA3 increased yield per vine, cluster weight, and berry weight. Vines sprayed three times had higher yields than treatments performed once or twice. Similar responses were determined for cluster weight and berry weight. Generally, treatments had beneficial effects on cluster length and width. This three-year study, on average, did not indicate impacts of either concentration or number of GA3 applications on cluster and berry number and shape as well as fruit soluble solids.
