I finished recording primary bud mortality in the Foundation Vineyard. Pruning formulas will be adjusted based on the mortality percentages.
Cultivar | % primary bud mortality* |
Cayuga White | 42% |
Chambourcin | 27% |
Chardonel | 30% |
Traminette | 5% |
Vignoles ** | 70% |
*Primary bud mortality was based on a 100 bud sample of live wood.
**Vignoles had over 50% dead one-year-old wood and the bud sample collected was only 39 buds due to limited availability of live wood in the fruiting zone.
