Effects of Different Periods Applied Fe~(2+) and Concentrations on Fe and Cd Contents in Iron Plaque on Rice Root
Bibliographic record
Abstract
The effects of different Fe 2+ concentrations(0,30,50and 70mg ·L -1 )on Fe and Cd contents in iron plaque of rice root at different growth stages(tillering,jointing,booting and fi lling)individually and continually were s tudied by a combined culture systemof Cd -polluted soil -sand -nutrient solution.The results showed that Fe contents in iron plaque in the treatments receiving Fe 2+ in nutrient solution culture were greater than that in control treatment (0mg ·L -1 )in solution culture,especially at both booting stage during rice growing period and after harvest.The change of Fe contents in iron plaque in the treatments at filling was greater than that in treatment at both tillering and jointing periods.The Cd contents in iron plaque of rice fo llowed the similar trend like iron.Fe contents in iron plaque in the treatments at all stages from t illering to filling were the highest at 50mg ·L -1 of Fe 2+ concentration compared with other Fe 2+ concentrations.Cd contents in rice root in the treatment at all stages fr om tillering to filling were well in accordance with Fe conte nts in iron plaque.

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.
