Other claims from this paper (10)
- Intervention effect Minimally pruned vines had a higher shoot number than hand-pruned vines.
- Intervention effect Minimally pruned vines had reduced leaf and shoot size compared with hand-pruned vines.
- Intervention effect Minimally pruned vines had a higher cluster number than hand-pruned vines.
- Intervention effect Minimally pruned vines had smaller berries than hand-pruned vines.
- Intervention effect Minimally pruned vines had fewer berries per cluster than hand-pruned vines.
- Intervention effect By canopy completion, canopy NCER was still 13 % higher in minimally pruned vines than in hand-pruned vines.
- Intervention effect Berry sugar concentration was not significantly lower in minimally pruned vines than in hand-pruned vines.
- Intervention effect Minimally pruned vines gave about 70 % higher yield than hand-pruned vines.
- Recommendation Minimal pruning is a valuable tool to improve the performance of Chardonnay vines under the experimental conditions.
- Association Canopy NCER in hand-pruned vines began to recover together with the transition to a faster shoot growth phase.
