Other claims from this paper (15)
- Observation Photosynthetic compensation did not occur after early leaf removal.
- Observation New leaves restored source capacity during slow berry growth.
- Intervention effect Leaf area per plant was similar at veraison in treated and control plants.
- Intervention effect Early leaf removal reduced berry growth.
- Intervention effect At the end of stage I, treated berries had half the fresh weight of controls.
- Observation Leaf removal affected pericarp cell size.
- Intervention effect Restored leaf area allowed treated berries the same relative growth rate as controls in stage III.
- Observation Growth rate compensation did not occur.
- Association Mature berry size was proportional to size before veraison.
- Intervention effect Leaf limitation shortened the first active berry growth period.
- Intervention effect Leaf limitation delayed ripening onset.
- Intervention effect At the first growth period end, treated juice had lower osmolarity, titratable acidity and malic acid.
- Intervention effect At the first growth period end, treated juice had lower soluble sugar concentration.
- Observation At maturity, organic acid and fructose concentrations were higher in LS berries.
- Intervention effect At maturity, osmolarity, titratable acidity and hexose accumulation rate were unaffected.
