Effects of enhanced ultraviolet-B irradiance on the diurnal variation of flavonoids in wheat leaves
Bibliographic record
Abstract
Pot cultivation experiments in greenhouse were conducted to study the effects of enhanced UV-B radiation on the diurnal variations of flavonoids in wheat leaves during grain filling stage. The results showed that the flavonoids content of wheat leaves increased significantly under the enhanced UV-B radiation at daytime, and then declined at night when they were released from the stress of UV-B radiation. Meanwhile, the difference of flavonoids content between control and UV-B treatment decreased gradually. The activity of phenylalanine ammonialyase also showed a similar trend with that of content of flavornoids. Simultaneously, the net photosynthetic rate of wheat was not affected by supplementary UV-B radiation, but the respiration rate was enhanced significantly at night. The results implied that the continuous fluctuation of flavonoids content might be another explanation why biomass was reduced significantly while plant net photosynthesis was not influenced by enhanced UV-B radiation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
