Abstract

fetched live from OpenAlex

In this paper,screening stage and threatening pressure of maize genotypes were studied under low nitrogen levels using solution incubation pot experiment.Here the main results of this study are presented:1.Under very low nitrogen level of 0.05 mmol/L,there were significant differences in N-deficiency,shoot dry weight,root dry weight,ratio of root weight to shoot weight and total nitrogen uptake among different maize genotypes,which readily assessed low nitrogen nutrition characters of maize genotypes.So,nitrogen level of 0.05 mmol/L is probably proper threatening pressure for screening low nitrogen maize genotypes.2.Guibi 303 genotype has high capacity to uptake nitrogen under low nitrogen threatening situation,and existing higher nitrogen utilization efficiency.But Miandan No.1,An'dan No.136 and Xinghuangdan No.89-2 all expressed stronger resistance to low nitrogen.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
