Juvenile productivity of five hybrid poplar clones and 20 genetically improved white and Norway spruces in boreal clay-belt of Quebec, Canada
Bibliographic record
Abstract
Similar to other boreal regions of Canada, northwestern Quebec has abundant lands available for the establishment of high-productivity plantations. However, few genetically improved species have been tested for this region. Three sites were planted with five hybrid poplar clones; 19 families of white spruce (Picea glauca [Moench] Voss) of southern Ontario and Quebec origins; 20 families of Norway spruce (Picea abies [L.] Karst.) of northeastern European origins; and a local seed source of white spruce. Survival and productivity were evaluated during their first three growing seasons. Survival rate was high for all selected plant material. For white spruce, genetically improved families were more productive than the local seed source. The use of exotics (Norway spruce or P. maximowiczii hybrids) did not confer any growth benefit at this early stage. Key words: survival, height, root collar diameter, field trial, exotic and native species

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.
