Efficacy of low O<sub>2</sub> and high CO<sub>2</sub> atmospheres in maintaining the postharvest quality of saskatoon fruit (<i>Amelanchier alnifolia</i> Nutt.)
Bibliographic record
Abstract
Changes in fruit quality of saskatoon (cvs. Pembina, Smoky, Northline, and Thiessen) stored under three O2 levels (2, 10, and 21%) factorially combined with two CO2 concentrations (0.035% and 5%) were assessed during 56 d of storage at 0.5 °C. The 5% CO2 atmosphere combined with 21 or 10% O2 was most effective at minimizing losses in fruit soluble solids, anthocyanins, firmness, and fresh weight. Fungal colonization of fruit after 8 wk of storage was eliminated in 5% CO2 at all O2 concentrations. Storage of fruit in 0.035% CO2 and 21 or 10% O2 resulted in the highest titratable acidity and lowest ethanol concentrations. Ethanol did not exceed 0.03% in fruit stored in any of the atmospheres. While changes in some of the quality characteristics of fruit during storage were cultivar dependent, differences among cultivars were small, and all four cultivars benefited from controlled atmosphere storage. Key words:Amelanchier alnifolia, saskatoon fruit, controlled atmosphere, postharvest quality

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.
