<i>In Vitro</i>Culture of Lowbush Blueberry (<i>Vaccinium angustifolium</i>Ait.)
Bibliographic record
Abstract
SUMMARY Cultures of three lowbush blueberry (Vaccinium angustifolium Ait.) clones collected from natural stands in Newfoundland were established in vitro on a modified cranberry (V. macrocarpon Ait.) tissue culture medium containing zeatin (5 μM) or N6-[2-isopentenyl]adenine (2iP) (10 μM). Shoot proliferation with respect to shoot number per explant differed among clones at various concentrations of zeatin over two culture periods. Best total shoot proliferation was obtained when basal nodal segments were cultured in the medium supplemented with 2-4 μM zeatin. In another experiment, nodal explants were more productive than shoot tips. Shoots growing for more than 12 weeks on media that contained more than 4 μM zeatin occasionally produced adventitious shoot masses, which appeared to arise from dense calli growing at the base of the shoots in the medium. The lower concentration of sucrose and lower irradiance improved shoot proliferation with respect to vigor compared to the control treatments (30 g L_1 and 30 μmol m∼2 s_1, respectively). In all experiments with subculture, there was an increase in shoot multiplication rate for all clones. A 50-100-fold multiplication rate was obtained every 3 months with the clones.

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.
