A study of different germination media for the 'Šampion' walnut cultivar pollen.
Bibliographic record
Abstract
Different culture media were tested in an attempt to improve the knowledge of the most suitable germination media for studying the in vitro pollen germination capacity of 'Sampion', a Serbian walnut cultivar. The research was conducted on agar media, as a four-factorial experiment, with different concentrations of agar (0.6%, 0.8% and 1%), sucrose (10%, 15% and 20%), H3BO3 (0 ppm, 200 ppm and 400 ppm) and CaCl2 (0 and 50 ppm). Pollen germination was maximized (39%) when the germination medium contained 0.8% agar, 15% sucrose, 400 ppm H3BO3 and 50 ppm CaCl2. Large and significant differences in pollen germination were observed in response to changing concentrations of agar, sucrose, boric acid and calcium chloride, and strong interaction was identified between all substances used.

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.
