The Influence of Growth Regulators on the Fertility of Seedless Tarnau Sort
Abstract: The research was conducted in experimental filial base of scientific research institute of horticulture, viticulture and wine-making named after academician. irzayev in 2012-2014. The object of the research is seedless sort of grape Tarnau for wine regionized in the republic of Uzbekistan and the scheme of plant layout in the experiment is 32, 5 m. Agrotechnical history of experimental plot is common in the republic. It has been stated in the research that the optimal concentration of processing grape with Gibberellin after 5 days from flowering stage of Tarnau was 100 mg/l. , under which additional yield per plantation square increased by 20, 3 % compared to unprocessed variant. Under the processing of more less concentration 25 mg/l the yield increased only by 12, 3 %. When Gibberellin was applied together with Dropp in 10mg/l, synergetic effect was not observed.
