Other claims from this paper (12)
- Intervention effect Leaf stripping removed 60% of upper canopy leaf area in Sangiovese.
- Intervention effect Leaf stripping removed 29% of upper canopy leaf area in Montepulciano.
- Intervention effect Total leaf area per vine fell 25% in Sangiovese.
- Intervention effect Total leaf area per vine fell 14% in Montepulciano.
- Intervention effect Leaf to fruit ratio fell from 1.18 to 0.73 m2/kg in Sangiovese.
- Intervention effect Leaf to fruit ratio fell from 1.23 to 1.03 m2/kg in Montepulciano.
- Intervention effect Defoliation did not affect yield per vine, bunch or berry weight in either cultivar.
- Intervention effect Defoliation did not affect must total acidity or pH in either cultivar.
- Intervention effect Defoliation reduced anthocyanins concentration in Montepulciano at harvest.
- Intervention effect Defoliation reduced polyphenols concentration in Montepulciano at harvest.
- Intervention effect Defoliation did not reduce anthocyanin or polyphenol concentration in Sangiovese.
- Recommendation The authors recommend testing late mechanical leaf removal on black-berried cultivars before large scale application because berry colour may suffer.
