La pousse courte, un indicateur du degré de maturation chez le hêtre (<i>Fagus sylvatica</i>L.)
Bibliographic record
Abstract
In beech, no external morphological characters that allow an understanding of how an individual stem gradually and continuously evolves from a juvenile vegetative stage toward a mature flowering stage, has ever been demonstrated. The only known traits are marcescence, indicating a juvenile stage, and flowering, indicating passage to adult stage. However, in young trees growing under a forest shadow, these markers are not visible since marcescence is not expressed and the trees are too young to flower. This study was conducted to find one or more external morphological characters that indicate the state of differentiation in beech. For that purpose, a simultaneous description of tree architecture and the short, 1-year-old, foliated growth units (u.c.) of the trees was completed. Analysis showed that the morphology of short u.c.'s evolved according to their localization in the plant, the age of the plant, and the environment where in which it is developping. Analysis also revealed that this evolution was directly related to growth in height of trees, but also and above all, to the degree of complexity reached during the trees' development. Thus, evolution of short u.c.'s is a scale on which some traits expressing internal plant potentialities (marcescence, flowering) can be localized.

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.
