Effects of pH on chlorophyll fl uorescence characteristics of two Syringa under water-logging stress
Bibliographic record
Abstract
In order to study the responses of Syringa to acid and alkali stress under the condition of water-logging stress, Syringa oblataand Syringa microphylla were taken a the tested materials, the potted culture experiments were conducted and the effects of 5 kinds of pH conditions on the chlorophyll content and chlorophyll fl uorescence characteristics of S.oblata and S.microphylla were studied. The results show that under the stress of water-logging, S.oblata's relative chlorophyll content decreased with fastest speed under alkaline stress, the extent of photoinhibition was strong under two stresses, the photosynthetic electron transfer rate was slower under acidic stress, no signifi cant changes in heat dissipation; S.microphylla's relative chlorophyll content decreased fastest under acidic stress, the heat dissipation increased fastest, the extent of photoinhibition was weaker under two stresses. Acid resistance of S. oblata's was strong and the alkaline resistance of S.microphylla's was strong under the stress of water-logging.

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.
