Effect of Nickel on Seed Germination and Seedling Growth of Ulmus pumila L.
Bibliographic record
Abstract
The ecological effect of nickel on seed germination and seedling growth of Ulmus pumila L was studied in this paper.The results showed that:the treatment with 1mg/L Ni 2+can enhance the seed vigor.The high concentration of(5,10mg/L)had significant inhibition on the growth of radicles.When Ni 2+concentration were higher than 50 mg/L,the seeds germination and growth were all damaged,leading to low seedling survival rate even unable to germinate.This suggested that low concentration of Ni 2+can promote seed germination and seedling growth,while exceeding certain density range can inhibit it.The range of inhibition of germination rate was near 10mg/L,radicle elongation inhibition threshold was in the 0-5mg/L range,hypocotyl elongation threshold was in the 5-50mg/L range.When soil was fertilized,nickel concentrations should not exceed 5mg/kg Ulmus pumila L.

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.
