Analyse des composantes de la croissance en hauteur et de la formation du tronc chez le chêne sessile,<i>Quercus petraea</i>(Matt.) Liebl. (Fagaceae) en sylviculture dynamique
Bibliographic record
Abstract
Simultaneous observation of morphological and anatomical markers allowed us to reconstitute the growth pattern of the main axis in two populations of sessile oak aged 15 and 29 years, respectively. The comparison of the morphological features of annual shoots and growth units according to either their ontogenic age or their year of formation allowed us to separate endogenous trends in the development of the tree and variations resulting from the effect of annual growth conditions. Three stages of tree development were identified. The first stage is characterized by the regular production of monocyclic annual shoots with a stable mean length and is typical of young trees growing under a dense canopy. In the second stage of development, the intrinsic growth pattern expresses itself dominantly; this stage is marked by a systematic increase in the length and polycyclism rate of successive annual shoots, and by a strong differentiation between the successive growth units of polycyclic annual shoots. In the third stage, environmental factors have a stronger influence on the ontogenic growth pattern. In this stage, the length of the different growth units and annual shoots is stationary but shows important annual variations, while the differentiation between the successive growth units of bicyclic annual shoots is not systematic.Key words: Quercus petraea, sessile oak, morphology, primary growth, ontogeny.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
