Effect of Pb,Hg Pollution on Germination and Antioxidant Activity of Three Kinds of Wheat Seeds
Bibliographic record
Abstract
In this paper,three kinds of wheat seeds were used as experimental material to study the effects of different concentrations of Hg+ and Pb2+ Pollution on the germination rate,germination vigor,the length of bud,antioxidant activity of them by the method of water culture.The results showed that the germination rate,germination vigor,the length of bud,antioxidant activity of three wheat were all inhibitied by Pb2+ polution.With the increasing of Pb2+ concentration,the inhibition gradually increased.Germination rate,germination vigor,the length of bud,antioxidant activity of agricultural wheat No.3 seed were all inhibitied by Hg+ pollution.and with the Hg+ concentration increasing,the inhibition gradually increased,but to agricultural wheat No.2 seed and new spring No.23,when Hg+ concentration were less than 50 mg/L,germination vigor had a little increasing,but had no effect on both the average length of bud and germination rate of the seeds.And when Hg+ concentration were higher than 100 mg/L,the germination rate,germination vigor,the length of bud,antioxidant activity of them were all inhibitied,and the higher of the concentration,the inhibition was the stronger.Antioxidant activity of three kinds of wheat seeds were all decreased in different concentrations of Hg+ pollution,and the higher of the concentration,the antioxidant activity of seedlings was the lower.When the Hg+ concentration was 300 mg/L,Pb2+ concentration was 500 mg/L,the germination of three wheat seeds were affected seriously.

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.
