Abstract
Taking pot cultivation Lespedeza davurica(Laxm.) Schindl as test material,the effects of enhanced UV-B radiations(0,1.944,3.002 kJ·m-2·d-1)on the content variation of UV-absorbing compounds and adjusting osmotic substances in the leaves were studied.The results showed that under the enhanced UV-B radiation,the contents of flavonoid,total hydroxybenzene,anthocyanin and the activity of phenylalanine ammonia-lyase increased at first and then decreased,and mostly they were significantly higher than that of the control(P0.05).Also due to different doses of UV-B radiation,the effects were slightly different.The increase extent(in the early stage of UV-B radiation) of the content of UV-absorbing compounds(exceptfor anthocyanins)and the activity of phenylalanine ammonia-lyase under 3.002 kJ·m-2·d-1UV-B radiation are significantly larger than that of 1.944 kJ·m-2·d-1 UV-B radiation(P0.05).The content of soluble protein decreased significantly under the enhanced UV-B radiation(P0.01),and decreased with the increasing of UV-B radiation.Only on the sixth day and under 1.944 kJ·m-2·d-1UV-B radiation the content of free proline was significantly higher than that of the control(P0.05),which was not found in the the rest cases.These results implied that the enhanced UV-B radiation induced the synthesis of the UV-absorbing compounds in the leaves of Lespedeza davurica,but inhibited the synthesis of the adjusting osmotic substances especially soluble protein.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
