Variation of syllepsis in eleven tamarack [Larix laricina (Du Roi) K. Koch] provenances in Northwestern Ontario and its relation with height growth / Deng Shaotang
Bibliographic record
Abstract
Variation in syllepsis of tamarack and its relationship to juvenile height \ngrowth in eleven tamarack provenances from northwestern Ontario was \nevaluated in a four-year-old clonal test planted at Thunder Bay, Ontario. \nSignificant provenance and clone-within-provenance effects were found for \nheight growth, and occurrence and degree of syllepsis. There existed a south-north \ntrend of decreasing provenance means for both height growth and \ndegree of syllepsis. Degree of syllepsis was found to be moderately \ncorrelated with current-year height growth. Provenance broad-sense \nheritability estimates ranged from 0.22 to 0.23 for 1989 final height and 1989 \nheight growth respectively, and they ranged from 0.11 to 0.13 for number and \nlength of sylleptic branches on 1989 height growth. Clonal broad-sense \nheritability estimates ranged from 0.16 to 0.18 for 1989 final height and 1989 \nheight growth respectively, and they ranged from 0.33 to 0.37 for number and \nlength of sylleptic branches on 1989 height growth. Although syllepsis of \ntamarack has high phenotypic plasticity, the potential for its development on \ntamarack is heritable. Syllepsis of tamarack may be an evolutionary \nmechanism that permits tamarack trees to deal with environmental uncertainty.

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.
