Alleviation Effects of Different Organic Acids on Induction and Growth of Rice(Oryza Sativa L.) Callus under Cu~(2+) Stress
Bibliographic record
Abstract
Using rice seed as material to study the alleviation effects of different organic acids on induction and growth of rice callus under oxidative stress induced by Cu2+.The result showed that different Cu2+ concentration in the MS culture medium inhibited evidently induction and growth of rice callus,and inhibitory effect increased with Cu2+ increasing.When Cu2+ concentration up to 1 000 μmol/L,the callus was small relatively,and its surface was hard and dry.Added organic acid,such as ascorbic acid and citric acid and oxalic acid,could improve significantly callus growth on condition that Cu2+ stress,especially with 250 μmol/L ascorbic acid was the best,the callus was fresh,light yellow,loose,the surface moist,close to controlled.Meanwhile,browning phenomenon was inhibited by ascorbic acid more effectively than the other two acids.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
