13 claims from these papers; 3 citations between them.
Papers whose results differ, checked claim by claim 2
2 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.
- Existing antioxidant levels are more important in acclimation to supplemental UV-B irradiation than inducible ones: Studies with high light pretreated tobacco leaves (2012)
decreaseWithout preceding high-light acclimation, UV-exposed leaves had 60% lower photosynthesis by treatment end.
Systemic antioxidant effects of low-dose ultraviolet treatment on tobacco leaves are mediated by hydrogen peroxide (2025)no changeLow dose UV had no significant photosynthesis effect in directly exposed leaves.

increaseThe authors concluded that adequate UV-B improved K326 net photosynthetic rate and assimilation capacity.
Effect of UV-B on growth and development and secondary metabolism of flue-cured tobacco (2009)decreaseUV-B moderately decreased net 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.
