Abstract

fetched live from OpenAlex

Using the pot culture with 10 maize landraces from Three Gorges Reservoir Areaas material,and investigated the main morphological and physiological traits at seedling stage under low nitrogen stress.The results showed that low nitrogen had a negative influence on seedling morphology and physiology to some degree,and there existed differences of maize landraces tolerant to low nitrogen stress.There were differences in tolerance to low nitrogen stress both among maize landraces with the same biological trait and different biological traits of a maize landrace.Based on the morphological and physiological characteristics of maize landraces under low nitrogen stress,number of laterials,root volume,total leaf area,and plant dry weight were suggested as morphological screening standards to identify the germplasm intolerant to low nitrogen,and nitratase activity and malondialdehye(MDA) content as physiological one.In addition,there is the rich landrace germplasm tolerant to low nitrogen in Three Gorges Reservoir Area,which could be used to genetically improve corn in breeding.

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.
