4 claims from these papers.
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.
- 201 Effects of CO2 Enrichment on the Growth and Stomatal Conductance of Two Cultivars of Bean (Phaseolus vulgaris L.) (2000)
increaseElevated CO2 (1200 μmol·m -2 ·s -1) raised dark-period stomatal conductance in each cultivar.
Influences of two CO2 concentrations and water availability on bean crop (2013)no changeHigh CO2 did not significantly change bean stomatal conductance.

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.
