Effect of abiotic stresses on primary / secondary metabolites and resveratrol in cv. Cabernet-Sauvignon

Abstract

The research was located at latitude 41° 01’ 11.15” N and longitude 27° 40’ 18.00” E, at an altitude of 60 m above sea level, with 15-year-old Cabernet-Sauvignon/110R vines over two years. The vineyard has a planting distance of 2.6×0.9 m, and the vines are trellised to double cordon Royat. In the vineyard, 4 abiotic stress applications (Shock Action, Leaf Injury, UV-C) including the Control were applied twice a day (morning and evening) for 5 days during 3 different phenological stages (Veraison, Veraison-Harvest, and Harvest). The Leaf Injury was performed once by striking the leaves with a rod. The Shock Action was carried out using a plastic hammer, and the UV-C was applied twice a day for 1 minute. As a result, it was determined that the abiotic stress did not cause significant differences in primary metabolites such as Total Soluble Solids (23.69°Brix) and Total Acidity (7.32 g L-1) but had an increasing effect on secondary metabolites (total tannin, anthocyanin, TPC, resveratrol). Additionally, it was found that they had an enhancing effect on the TPI. In terms of resveratrol, the effects of UV-C (0.35 mg kg-1) and Leaf Injury (0.27 mg kg-1) were noted to be higher than the other two (Shock Action and Control).
