The influence of gibberellin acid (GA)3 on production and quality of the grapevine cultivar Vlosh was studied during the 2011-2012 period. Different doses (75-100-125 mg / l-) of GA3 were applied and the effects on the percentage of sugar, acceleration of ripening and berry size were analyzed. Results confirmed that all treatments showed an acceleration of the flowering and maturation compared to controls. Simultaneously, commercial appearance and performance were improved, and sugar content was increased 0.6 - 4.2% compared to control and ripening was accelerated 18 days. Gibberellins affected biometric indicators such as the growth of the berry, size and weight, as a result of development biosynthesic processes. Treatment of this cultivar with phytohormone GA3 during affected in some extent reducing the seed number per fruit of the grapevine. Biosynthetic processes are of enzymatic and biochemic nature and developed with vitamine and phytohormons contribute. Application of phytohormone with concentration 125 mg /l-1 induced ripening of grapes about 10 days before control. [ABSTRACT FROM AUTHOR] |
