Abstract

This study examined how some physicochemical properties of Gemlik olives (Olea europaea L. cv. Gemlik) grown in five different regions of Türkiye (Antalya, Aydın, Balıkesir, Manisa, and Hatay) differed during two harvest seasons. The study was conducted to find out how changes in climate, soil composition, and leaf nutrients in the different regions affect fruit ripening, oil accumulation, and fruit pigmentation. Water, dry matter, oil, chlorophyll, and carotenoid contents analyses were performed on Gemlik olives. Balıkesir olives yielded the most oil (64.04% and 57.10% of dry weight), but Aydın and Manisa olives yielded less oil (16-17% of dry weight). Hatay had the most pigments (40.64 mg/kg chlorophyll and 235.63 mg/kg carotenoids). Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) showed that oil and pigment changes are linked to environmental factors such as temperature, salt, and soil magnesium. This study ties in with the UN Sustainable Development Goals (SDGs 2, 12, and 13). It will also ensure quality and resilience to climate change within Protected Designation of Origin (PDO) systems.
