Study on Photosynthetic Characteristics and Diurnal Course of the Endangered Species Paeonia ludlowii
Bibliographic record
Abstract
In this research,the most advanced system for portable photosynthesis system-Li-cor-6400 was used in Paeonia ludlowii which was one kind of rare and endangered species.The diurnal course of net photosynthetic rate of P.ludlowii showed a single peak in natural environment conditions,which reached a peak at 11:30 O'clock.There existed no midday depression in its photosynthesis.At 12:30 O'clock,the value of stoma limitation and water pressure saturation deficits of leaf reached their peaks,while water use efficiency was not high,with a highest value appearing at 10:30 O'clock.The maximum value of apparent quantum yield appeared at 10:30 O'clock.However,the climax value of transpiration rate appearing at 12:30 O'clock,was not coordinate in time with maximum value of photosynthetic rate,which showed that lots of factors affected photosynthetic rate of P.ludlowii under special climate factors in Tibet.In the diurnal course of photosynthetic rate of P.ludlowii,high value [over 4.00 μmol/(m2·s)] had kept on for 9 hours or so,which was very easy for P.ludlowii to accumulate photosynthetic products,and it showed that P.ludlowii was a type of light plant.Generally,it offered scientific foundation for taming medical or ornamental plant of wild Ranunculaceae Paeonia by studying the photosynthetic characteristics and diurnal course of P.ludlowii.

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.
