Özet:

In this study, it was aimed to determine the physical changes of seven different colored table grape varieties in the samples taken at different periods until the ripening time. The cultivars used in the study are Alphonse Lavallée, Royal, Tekirdağ Çekirdeksizi, Michael Palieri, Karaerik, Bilecik İrikara and Horoz Karası. Grape samples were harvested for four weeks (20.08.2019, 27.08.2019, 02.09.2019 and 09.09.2019) every week for approximately one month until ripening. Cluster weight, bunch length and width, berry weight, berry width-length and berry hardness values were taken from the harvested grapes. Horoz Karası variety attracted attention with its cluster weight (550.86 g) and cluster width (15.01 cm) characteristics. The Michael Palieri variety stood out with its berry weight (8.92 g) and the Alphonse Lavallée variety with its berry hardness (0.94). Physical characteristics of all cultivars from fall to maturity differed according to both periods and cultivars. While the varieties and periods used in the study serve the literature, they are also an infrastructure for different studies with more varieties, different locations and different periods.
