Abstract
The production of black spruce ( Picea mariana (Mill.) \nB.S.P.) bare root stock in Ontario nurseries presents two \nmain problems. First, seedlings at the end of the first \ngrowing season are small, and thus susceptible to frost \nheaving. Second, it takes a long time, 3 years, to produce \nshippable seedlings. Trying to solve these problems the \nMinistry of Natural Resources Thunder Bay Nursery is \ntesting an accelerated transplant system. Seedlings are \nsown in a greenhouse in a mini-container and after 10 weeks \nare transplanted outdoors for two growing seasons. There is \na winter and a summer crop from the greenhouse each year. \nThe objective of this paper was to evaluate the effect of 3 \nfactors on summer crop seedlings. The 3 factors were SOWING \nDATE (levels: July 5, 15, 25, and August 4), the duration \nof an initial 18-h LONG DAY treatment (levels: 7, 10, or 13 \nweeks), and the duration of a subsequent 8-h SHORT DAY \ntreatment (levels 0, 6, or 12 days). Finally, all \nseedlings were held under natural photoperiod until the \ntotal length of the SHORT DAY and natural photoperiod \ntreatments was 11 weeks. Bud initiation was monitored \nduring this 11 week period. Bud diameter, number of \nprimordia, basal caliper, and root dry weight were measured \nimmediately prior to placing the seedlings in cold storage \nfor the winter. LONG DAY was the most important factor. \nSeedlings that received the ten-week LONG DAY treatment gave the \nbest response. Even though 13-week LONG DAY seedlings \nwere significantly taller, 10-week specimens showed a \nsimilar bud diameter and basal caliper, as well as \na significantly heavier root dry weight, and more \nprimordia. Eventually, the containers were too small for \n13-week LONG DAY seedlings that showed a potbound \nsituation. Although there were some significant \ndifferences, the various levels of the factors SOWING DATE \nand SHORT DAY did not produce any considerable effect on \nthe growing regime. At the end of the first growing season \nin nursery beds, seedlings from the best treatment \ncombinations of the summer crop reached almost a shippable \nsize. This confirms the feasibility of the studied system \nto produce bare root stock in two years or less.

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 it
