Effects of various clones of the Kober 5BB rootstock on the productive and technological properties of the Italian riesling variety in the ad Vršac vineyards
Uticaj različitih klonova lozne podloge Kober 5BB na proizvodne i tehnološke karakteristike sorte rizling italijanski u vršačkom vinogorju
Abstract
The study was carried out in the AD Vršac vineyards, Serbia during the 2000- 2004 period. The vineyard was established in the location of Crvenka in 1989 with the row distance of 3 x 1 m. The vine was grown in rows with a two level cordon-shaped root to which a mixed cut was applied. The Italian Riesling variety was transplanted on the clones of various rootstocks of the Kober 5BB, clone 114 and 13; SO4 clone 31 and 74; Teleki 5C clones 6-16, 6-52, 6-53 i 10; 41B clones 86, 87 and 88. The study encompassed the clones 114 and 13 Kober 5BB and their properties were observed during the period of full vineyard fertility. The obtained results indicate that the used clones of the rootstocks positively affected the observed properties: grape yield, sugar content, total acid, glucoacidimetric index of the grape yield. The best results were detected in the clone 114, then in the clone 13 and at last in the Kober 5BB control that prevails in this location.
Istraživanja su obavljena u periodu 2000-2004. godine u proizvodnom zasadu AD Vršački vinogradi. Vinograd je podignut 1989. godine na lokaciji Crvenka sa razmakom sadnje 3x1 m. Loza je gajena špalirski sa visokim stablom u vidu dvospratne kordunice uz primenu mešovite rezidbe. Vinska sorta rizling italijanski okalemljena je na klonovima različitih podloga kober 5BB, klon 114 i 13; SO4 klon 31 i 74; Teleki 5C klonovi 6-16, 6-52, 6-53 i 10; 41B klonovi 86, 87 i 88. Ovim istraživanjem bili su obuhvaćeni klonovi 114 i 13 kober 5BB, a praćena su i njihova svojstva u fazi pune rodnosti vinograda. Postignuti rezultati ukazuju da su primenjeni klonovi loznih podloga ispoljili pozitivan uticaj na praćena svojstva: količina prinosa, masa grozda, sadržaj šećera, ukupne kiseline i glukoacidimetrijski indeks zrelosti grožđa. Najbolje rezultate dao je klon 114, zatim klon 13 u odnosu na standardu varijantu lozne pologe kober 5BB koja je dominantna na ovoj locaji.
