Primary metabolites are essential for plant growth and development, whereas secondary metabolites, such as phenolic compounds, aid in biotic and abiotic stress responses and offer significant health benefits. Phytoalexins are secondary metabolites with diverse chemical structures across plant species, including resveratrol. The aim of this study wa...

In recent years, climate change and global warming have become significant factors in viticulture, as in many plant cultivations. High-altitude cultivation affects grapevine physiology and composition, offering alternatives for improved viticulture. The aim of this study was to determine of the phenolic content, antioxidant activities and pomologic...

This study aimed to evaluate the synergistic effect of preharvest spraying with alginate and in combination with salicylic acid (SA) and oxalic acid (OA), on the quality parameters and storage life of ‘Red Globe’ grape variety at 0-1°C with 85-90% relative humidity for 60 days. Data of physical and chemical quality parameters were taken at 15-day i...

This study aimed to review the current knowledge about cv. ‘Ada Karası’ and its wine, including oenological features and terroir characteristics gathered during geographical indication labelling studies. The research analyzed the climate and soil characteristics to determine the terroir properties of cv. ‘Ada Karası’. Furthermore, existing data on...

The aim of the research was to determine the impact of regulated deficit irrigations (RDIs) on the accumulation of chlorophyll, proline, and abscisic acid (ABA) in grapevines. Cuttings of Vitis vinifera L. cv ‘Adakarası,’ ‘Papazkarası,’ ‘Karasakız,’ ‘Karalahana,’ ‘Yapıncak,’ ‘Vasilaki,’ ‘Cabernet Sauvignon,’ and ‘Sauvignon Blanc’ were treated to di...

Aronia as a berry species has high antioxidant capacity and anthocyanin content. It yields in the second year after plantation, and its fruits, which can be processed and consumed freshly, are sold at quite good prices. Aronia has been cultivated in Turkey, where the aronia industry is considered to grow with the increase of its production in Turke...

In recent years, medium moisture products have been preferred because their eating quality is close to fresh products and their durability is longer than fresh products. Medium moisture products have high moisture content and, accordingly, water activities and are suitable for microbiological deterioration. Tekirdağ Misketi grape variety, which was...
