Other claims from this paper (8)
- Intervention effect Girdling increased stomatal conductance at harvest.
- Intervention effect Girdling decreased glutamine concentration at harvest.
- Intervention effect Girdling increased anthocyanin concentration in skin and pulp at harvest.
- Observation Berry weight declined 27% from 181 days after pruning to harvest.
- Intervention effect Girdled vines had significantly higher berry weight at 181 days after pruning.
- Intervention effect Sugars, organic acids and other amino acids did not significantly differ with girdling.
- Intervention effect Girdling affected more secondary metabolites in skin and pulp than in seeds.
- Recommendation The authors propose commercial girdling to improve berry color and phenolics.
