Objective
The objective of this study was to determine the most suitable American grapevine rootstocks in Sazgin vineyards for Dokulgen, Honusu and Dimiski grape varieties grown widely in Gaziantep ecology.
Materials and Methods
Dimiski for dried grape, Dokulgen for raisin wine and table, Honusu for table budded on 8 American grapevine rootstocks (1103 Paulsen, 140 Ruggeri, 110 R, Rupestris du lot, So4, 41 B, 420 A, 44-53) were used for treatments. 7 observations and analysis were done during the project and the affinity examples were calculated by Branas’ method (1974).
Results
The rootstocks of Paulsen 1103, Rug 140 and 110 R were adopted better to the regional ecology andincreased the number of bunch and the weight of bunches in all budded varieties.The productivities of rootstocks of Ruggeri 140, and Paulsen 1103 in Dimiski varieties, Paulsen 1103, 110 R, and in Dolukgen varieties, and Rug 140, Paulsen1103 and 110 R in Honusu varieties were found to be the greatest amounts of 9.3 and 8.4 kg/vine, 6.2 and 5.5 kg/vine, and 6.8, 5.6, and 5.4 kg/vine, respectively.The weights of 100 fruits of Dimiski and Honusu positively effected by Paulsen 1103, Dokukgen positively effected by SO4 and Rup du Lot were found to be 442 and 371 g and 243 and 259 g.The effects of the rootstocks on the percentage of total solid materials of Dimiski were found to be not significantly affected but the SO4 rootstocks was found to be effective on Dokulgen to increase its total solid content to 18.4%. The efficiencies of rootstocks on raisin wine and acidity in all varieties were found to be not significant.The differences between affinities of the rootstocks and Dimiski, Dokulgen, and Honusu was found to be not statistically significant. The affinity ranging 4 to 7 caused swelling of the above of the budding point which showed not ideal affinities of rootstocks and varieties, however this situation did not effected the yield and developments of varieties.The results showed that The rootstocks of ruggeri 140 and Paulsen 1103 for Dimiski, Paulsen 1103 and 110 R for Dokulgen, and Ruggeri 140, Paulsen 1103, and 110 R for Honusu were found to the most suitable rootstocks.
