Evaluation of Yields and Quality of Saplings Obtained by Grafting Combinations of Different American Grapevine Rootstocks and Kalecik Karasi Grape Variety

Abstract

Cultivation on American grapevine rootstocks, which have been found to be an effective solution against phylloxera pest, which is the biggest threat to vineyard areas, has brought along the necessity of examining the affinity between rootstock and scion. In this regard, to increase the amount of current vineyard production by adding a new research to the studies examining the affinity situation in the literature, scions belonging to Kalecik Karası grape variety were grafted on 10 different rootstocks (41B, 5BB, 1103P, SO4, 99R, 1616C, 1613C, 5C, Ramsey ve Harmoney) by omega bench grafting method, and sapling yield and quality characteristics were examined in greenhouse conditions for two years in duplicate. After the measurements carried out in both years, it was determined that the average degree of callus formation of the combinations formed trough different rootstocks was 3.45, the length of the saplings was 10.90 cm, the number of leaves was 5.71 and the total sapling yield was 78%.
