10 pairs of papers on this question report results that differ: an effect in one paper, the opposite effect or no effect in the other. Two model reviewers reading both claims accepted each pair.
- Effect of berry Thinning, CPPU spraying and pinching on cluster and berry quality of two grapevine cultivars (2009)
decreaseGA3 at 1.5 or 3.0 ppm spraying significantly decreased berry number, weight and cluster compactness compared with untreated vines.
FLAME SEEDLESS GRAPE VARIETY (Vitis V inifera L.) AND DIFFERENT CONCENTRATION OF GIBBERELLIC ACID (GA 3 ) (2014)increaseGibberellic acid at 20 mg/L increased cluster and berry weight.

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.
