Effects of Simulated Acid Rain on Seed Germination and Seedling Growth of Oenothera speciosa
Bibliographic record
Abstract
Seeds of Oenothera speciosa were selected as experimental materials,effects of simulated acid rain on seed germination and seedling growth were studied by simulating acid rain solution with different p H values. Results showed that,seed germination and seedling growth of Oenothera speciosa were suffered different influences under acid rain stress. Only 5 percent of seeds germinated when p H values was 2. 5. Germination energy,germination rate and vitality index significantly dropped under acid rain stress with p H value from 2. 5to 3. 0,while it had no significant effect on germination energy and vitality index under other treatments,but the growth of roots of Oenothera speciosa seedlings was greatly inhibited under all of the p H values. Only when p H value was 2. 5,seedling shoot length and fresh weight significant decreased. So it had no significant effect on seed germination of Oenothera speciosa under p H value higher than 3. 5,but it was greatly inhibited under p H lower than 3. 0. and the growth of root was most sensitive to acid rain stress.

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.
