Papers whose results differ, checked claim by claim 4
4 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.
- Growth and Gas Exchange of Three Sorghum Cultivars Under Drought Stress (2003)
decreaseWater stress reduced net photosynthetic rate, stomatal conductance and transpiration rate least in Gadambalia and most in Tabat.
EFFECTS OF HEAT AND WATER STRESS AND THEIR INTERACTIONS ON GRAIN SORGHUM (SORGHUM BICOLOR (L.) MOENCH) (1982)increaseWater stress at -0.3 and -0.45 MPa gave greater leaf photosynthetic rates than the controls.

decreaseDrought-associated senescence involved decreasing photosynthesis, Fv/Fm and chlorophyll content.
Changes in Grain Sorghum Stomatal and Photosynthetic Response to Moisture Stress across Growth Stages1 (1984)no changePhotosynthesis per leaf area was not decreased by water stress in reproduction and filling.

decreaseOsmotic stress decreased sorghum photosynthetic rate.

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.
