Growth-promoting Effect of Graphene Oxide on Tissue Culture Seedlings of Poplar
Bibliographic record
Abstract
Graphene oxide (GO) is a widely used nanomaterial, whose unique carbon-based structure bears abundant oxygen-containing functional groups. An increasing number of investigations have been performed on the effects of GO on plants due to its extensive use in various fields. In this work, under the optimized GO concentration (6 mg/L), we found that GO promoted the growth rate of the root of poplar. TEM images depicted that the plasmolysis and an increased number of starch grains were the two major physiological changes in the root cell samples. GO adhered to the cell membrane on the inner side of the cell wall and enhanced the toughness of the adventitious root. And the activity of oxidoreductases were measured and SOD, POD were found to increase significantly compared with the control group, but the increase of CAT was not obvious. Related gene expression was enhanced at low concentration of GO, but inhibited at high concentration. Our results indicate the possible usage of GO as enhancers in the growth of poplar tissue culture 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.
