Positional influence on rooting of shoots forced from the main bole of swamp white oak and northern red oak
Bibliographic record
Abstract
The transition of ontogenetic maturity was assessed in two oak species by forcing softwood shoots from main bole stem sections in the greenhouse and from intact crowns, stumps, and hedged trees in situ and subsequently subjecting the new shoots to rooting trials. Mean shoot production was greater from forced stem sections of northern red oak (Quercus rubra L.) than from those of swamp white oak (Quercus bicolor Willd.) (14.6 and 4.6 shoots/m, respectively). Northern red oak stem sections exhibited a vertical gradient in the number of forced shoots; greater numbers originated from basal and juvenile sections of trees than from distal and mature sections. Rooting of swamp white oak shoots was low, 1.4% for forced shoots and none from hedged trees. Rooting of northern red oak was greater but variable, averaging 40.3% from greenhouse forced shoots and 0-35% from field-grown trees. Moreover, percent rooting was greatest for forced shoots originating from basal stem sections and declined with increasing distance from the tree base. The results suggest that ontogenetic maturation gradually increases, and rooting response decreases, along the bole of northern red oak trees.

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.
