Effect of Seed Number on Seed, Berry and Quality Characteristics of Grapes

Grapes are one of the most preferred berries with high nutritional value, delicious and refreshing. In table grapes, taste and aroma and berry size are among the primary reasons for preference. It is known that the seeds in grapes have important effects especially on berry size. In our study, the effects of the number of seeds in Red Globe grape variety berries on seed berry characteristics and quality parameters were examined. It was determined that the majority of the berries in the bunches of Red Globe (83.44%) had 2, 3 and 4 seeds. It was determined that the number of seeds in the berries had important effects on seed characteristics. The length, width and weight of the seeds obtained from the berries with three seeds were lower than the others. Parallel to the increase in the number of seeds in the berries, increases in berry weight, length and width occurred. In addition, the increase in the number of seeds increased berry detachment and skin rupture force. While the increase in the number of seeds improved berry properties, it decreased SSC and increased TA in berries with more than three seeds. In terms of color parameters, chroma and hue values showed significant differences in berries with different numbers of seeds. As a result of the study, it is thought that the formation of three seeds in berries for the Red Globe grape variety is at a more desired level for quality and seed properties compared to other seed numbers. In the light of the results we obtained, it was concluded that determining the seed numbers of the varieties is important in order to determine their effects on berry characteristics and quality parameters in other table seed grape varieties.
