- Girdling improved berry coloration in summer but suppressed return growth in the following spring in 'Kyoho' grapevines cultivated in the subtropical double cropping system (2015)
increaseGirdling improved total soluble solids in own-rooted vines in summer.
The Influence of Girdling and Gibberellic Acid Application at Fruitset on Ruby Seedless and Thompson Seedless Grapes (1987)decreaseGirdling reduced soluble solids concentration at harvest by 0.8°Brix.

A paper is on the positive side when any of its claims here is positive. Claims are grouped by organism, treatment and what was measured or targeted. Claims that compare genotypes are left out; a claim about lacking a nutrient counts the other way round in that nutrient’s question. “Results differ” marks a question where two model reviewers, reading both claims, accepted at least one pair of papers whose results differ.
