Papers whose results differ, checked claim by claim 1
1 pair 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.
- The Effect of Ethephon on Onion Seedstalk Height and Seed Production Characteristics1 (1975)
no changeEthephon did not affect onion seed weight or seed germination.
Effect of plant growth regulators on growth and seed yield of onion (2025)increaseEthephon at 200 ppm significantly improved seed weight per primary and secondary umbel.

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.
