Nitrogen uptake during the leafless period in juvenile plants of a winter-green perennial herb, <i>Lycoris radiata</i> var. <i>radiata</i> (Amaryllidaceae)
Bibliographic record
Abstract
Leafless plants are often assumed to be in a dormant stage with low physiological activity. However, having an ability to take up nutrients during the leafless period may be beneficial if nutrient availability is high during that period. We examined a winter-green geophyte, Lycoris radiata var. radiata, to determine whether it maintained root activity during the leafless period for this species (from June to September in central Japan). The species had roots throughout the year, but new roots emerged mainly during the leafless period. The new roots took up applied nitrogen during the leafless period. The annual maximum rate of root respiration occurred in July. These results suggest that the leafless period is not a dormant period for L. radiata var. radiata; instead, it is a period with high root activity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
