摘要

In 1996 and 1998, the grape cultivars Welschriesling, Furmint, Riesling, Chardonnay, Sauvignon blanc, Muller-Thurgau and Kerner were grafted onto the rootstocks Borner and Kober 5BB. In total, 200 scions of each cultivar were grafted onto each rootstock. In 1996, the average percentage of grafted vines with completely developed callus was 10% higher using Kober 5BB, except for Sauvignon blanc. The number of grafted vines with partially developed callus was higher when Borner was used. The greatest difference among rootstocks was observed for Chardonnay. In 1998, the average percentage of grafted vines with completely developed callus was higher than in 1996 for both rootstocks and all cultivars. After forcing, the average percentage of grafted vines with completely developed callus was higher in Kerner, Welschriesling, Riesling and Sauvignon blanc on Borner. In both years, the significant impact of Borner was found only in the cause of Sauvignon blanc. For the other cultivars, no significant differences between rootstocks were observed in 1998. The average percentage of first-grade grafted vines in both years was highest when Kober 5BB was used. It varied from 61.2% for Riesling to 70.2% for Welschriesling. In the case of Borner, this percentage was lower and ranged from 49% for Riesling to 59.8% for Chardonnay. In 1996, there were significant differences between rootstocks for all cultivars. Differences among rootstocks were observed for root development. Approximately 39.3% of the grafted vines on Kober 5BB had 3 roots and 60.7% had 4 or more roots. For Borner, 63.1% of the grafted vines had 3 roots and only 36.9% had 4 or more roots.
