Study on the Sensitivity of Saussurea involucrate to Hygromycin During Tissue Culture
Bibliographic record
Abstract
To study the effects on induction,growth and differentiation of callus(Saussurea involucrate),the hygromycin and Saussurea involucrate leaves were used as stress and explants,respectively.Cultured on MS+ NAA 2.00 mg/L+6-BA 1.00 mg/L media added different concentration(5 mg/L to 50 mg/L) of hygromycin,the result showed that hygromycin of 8 mg/L was the best concentration for screening calli,there were significantly inhibition on callus induction and growth,and the damagement increased with the concerntration rise of hygromycin,the callus was greatly damaged and it's characters were small,browning and dying with the concentration of hygromycin up to 20 mg/L.Meanwhile,the low concentration(0.5 mg/L to 2 mg/L) of hygromycin could enhance the rate of callus differentiation,the averge frequcnce of callus germination was up to 98.33% on the medium of callus induction added 0.5 mg/L hygromycin.

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.
