Stady on Enhancement of Chilling and Drought Resistance in Tobacco Seeds and Seedlings by Seed Priming with Gibberellin
Bibliographic record
Abstract
In this study,seeds of tobacco was taken as experimental materials,using 0. 05,0. 10,0. 15,0. 50,1. 00 mmol / L of gibberellin( GA 3) to prime tobacco seeds,and the priming effects on seed germination and seedling growth under normal culture,drought,low temperature,and drought-low temperature cross stress were studied. The Results showed that the seed priming with GA 3 could improve significantly the germination potential,germination rate and germination index of tobacco seeds,shorten germination time,increase the root and shoot length,and fresh and dry weight of tobacco seedings under normal culture,drought,low temperature and drought-low temperature cross stress conditions,and the best obtained effects was in with 0. 5 mmol / L GA 3 the present experiments. As a conclusion,the seed priming with gibberellin could enhance simultaneously the chilling and drought resistance of tobacco seeds and seedlings.

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.
