Abstract

fetched live from OpenAlex

Through adding different concentrations of La to the soil which collected from copper tailings yard,this paper studied the effects of La on tolerance and accumulation of Lolium perenne under higher concentration of Cu stress.The results showed that La promoted the germination of L.perenne in low concentration of Cu while inhibited in high concentration.The germination rate,germination index,biomass and tolerance index were inhibited significantly with control group(P 0.05) when the concentration of La was up to 100 mg kg-1.The length of leaf and stem,length of root,weight of leaf and stem and weight of root were inhibited by La,and the average inhibiting rates were 11.90%,12.62%,7.21%,13.78% and 13.33%,respectively.The inhibition of La on the growth of root was stronger than that of leaf and stem.The average inhibiting rate of root weight was 2.77% higher than those of leaf and stem,while the inhibiting rate of root length was 6.75% higher than leaf and stem.The content of Cu in L.perenne was increased with the increasing of La concentration.It increased 8.49% and 6.99% in above ground and root respectively.In conclusion,the treatment of added La could enhance the accumulation and transportation of Cu in L.perenne in copper tailings yard.

Teacher imitation

Not 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.
