Abstract
In a long-term experiment with ‘Chardonnay’ the influences of 31 rootstock cultivars on yield, cluster weight, must weight, titratable acidity in the must, pH-value of the must, pruning wood weight and occurrence of chlorosis were determined.
The test site was a carbonate containing brown soil on flyschmarl with 18 to 40% lime content and medium lime tolerance.
On average over the 21 experimental years (2001 to 2021) ‘1103 P’, ‘G 26’, ‘Riparia Portalis’, ‘725 P’, ‘Ganzin 1’, ‘Aripa’ and ‘779 P’ had a significant negative effect and ‘420 A’, ‘R 27’, ‘Binova’, ‘41 B’ and ‘SO4’ had a significant positive effect on yield.
Cluster weight was significantly reduced by ‘1103 P’, ‘725 P’, ‘G 26’ and ‘779 P’ and significantly increased by ‘420 A’, ‘Börner’, ‘R 27’, ‘Binova’, ‘Teleki 5C’, ‘41 B’, ‘3309 C’ and ‘SO4’. ‘Ru 140’, ‘Ganzin 1’, ‘41 B’ and ‘EM 33’ had a significant reducing effect on the sugar content in the must.
Acidity in must was significantly reduced by ‘Riparia Portalis’, ‘G 26’, ‘Grézot 1’, ‘Aripa’, ‘101-14’, ‘R 7’ and ‘3309 C’ and significantly increased by ‘Börner’, ‘125 AA’, ‘R 27’, ‘1616 C’, ‘99 Richter’, ‘EM 33’, ‘779 P’, ‘Cosmo 2’, ‘Binova’, ‘225 Ru A2’, ‘Ru 140’ and ‘41 B’. Pruning wood weight was significantly decreased by ‘Aripa’, ‘Riparia Portalis’, ‘3309 C’, ‘101-14’, ‘G 26’, ‘110 R’, ‘1616 C’, ‘Ganzin 1’, ‘Börner’, ‘SO4’, ‘Cosmo 10’ and ‘Binova’ and significantly increased by ‘R 7’, ‘99 R’, ‘725 P’, ‘225 Ru A2’, ‘Fercal’, ‘125 AA’ and ‘Cosmo 2’. Among these, ‘Aripa’ and ‘Riparia Portalis’ had the weakest growth by far.
By the 25th year of growth between 6.7% (‘SO4’, ‘R 7’, ‘99 Richter’, ‘1616 C’) and 46.7% (‘G 26’) of the vines had failed, depending on the rootstock cultivar.
Chlorosis did not occur or only occurred to a very small extent.
