Интродукция сосны скрученной в условиях Ленинградской области
Bibliographic record
Abstract
The paper studied the growth of 22-year-old Pinus contorta stands in the Leningrad Region. These trees are half-sib offsprings of five different plus trees from their native habitat (Alberta, Canada). We have carried out a comparative analysis of sowing qualities of Pinus contorta seeds at primary introduction and local species ( Pinus sylvestris ). The research resulted in some preliminary conclusions about the level of adaptation of Pinus contorta at its introduction in the Leningrad Region. Since planting and up to the second age-class, the fastest height growth was observed in Pinus contorta offsprings from Gordondale community, and the fastest diameter growth was observed in the offsprings from Swan Hills. Seed germination in introduced species varied from 23.5 to 68.7 %. The best germination results were observed in the seeds of Pinus contorta offsprings from Grovedale hamlet. The amount of empty seeds in the offsprings under study varied between 14 and 41.8 %, suggesting the need for additional seed separation before sowing and further research on the properties of Pinus contorta pollen in Northwest Russia.

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.
