Description
Summary:Regional climatic conditions can have a dramatic effect on the degree and rate of natural grape coloration and quality parameters. In this study it was aimed to evaluate effect of the climate for Red Globe variety cultivated in Lakes Region which is in Eğirdir town of Isparta city in Turkey. Red Globe grape variety was evaluated for quality and especially for berry skin coloration and cold storage ability. Study was done between 2013–2015. Vineyard was designed according to randomized block design with three replicates. Rational pergola system was used. Excellent berry coloration for Red Globe grape variety was determined and average quality parameters yield per vine (7.0–9.8 kg), soluble sugar content %16.–17.6) titratable acidity (4.2–4.4 g/lt), single berry weight (9.0–10.2 g), and phenological observations were done. Yield and other quality parameters were evaluated well in this period. Grapes were stored in cold storage (NA) conditions with SO2 and without SO2 pads after harvest. Quality changes were determined in storage period by 1 month interval, it was carried out with weight loses, fruit skin color, fruit firmness, total soluble solids, pH, titratable acidity, sensual evaluations, microbiological and shelf life analyzes. It was evaluated that with SO2 pads Red Globe variety can be stored commercially up to 90–100 days. It was determined that climate of the region had a good positive effect on the excellent coloration and quality parameters and cold storage performance of the Red Globe.
