Abstract
Plant growth regulators may have different physiological effects depending on the application stage and concentration when applied externally. In this study, it was aimed to determine the effects of pre-harvest aminoethoxyvinylglycine applications on the mineral contents of Vitis vinifera L. cv. Alphonse Lavallée leaves. AVG was applied to vines at five different concentrations (0, 250, 500, 750 and 1000 mg L-1) and two application stages (at full bloom and fruit set). As a result, the effects on macro elements content of the grapevine of AVG applications were significant except P. In terms of microelement contents, generally, microelement contents were increased with the AVG applications, only the amount of Fe decreased with the AVG applications. For this reason, AVG plant growth regulator is thought to have both increasing and decreasing effects on the mineral element contents of Alphonse Lavallée leaves.
