e1“Experiments were conducted to evaluate the effects of three pruning levels (20, 30 and 40 nodes per vine) and three fruit-zone leaf removal levels (0%, 50%, and 100%) on the yield and fruit quality of Frontenac gris and Marquette wine grapes in a northern production region”
e5“Frontenac gris fruit quality was similar both years and was not influenced by pruning or leaf removal levels”

Other claims from this paper (9)
- Intervention effect Retaining more buds per vine increased yields in both cultivars.
- Intervention effect Retaining more buds per vine reduced pruning weights in both cultivars.
- Intervention effect Yields of Frontenac gris and Marquette were greatest when 50% of the fruit-zone leaves were removed.
- Intervention effect Individual berries in clusters were heavier when vines were pruned to retain 40 buds.
- Observation Frontenac gris fruit quality was similar across both years of the study.
- Association Marquette fruit total soluble solids content was greater in 2012.
- Intervention effect Marquette fruit titratable acidity was lower when 100% of the fruit-zone leaves were removed.
- Recommendation The authors judge that 100% fruit-zone leaf removal was too severe.
- Recommendation Greater bud retention levels should be investigated in the two cold-hardy hybrid wine grapes.
