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 O 2 levels (2, 10, and 21%) factorially combined with two CO 2 concentrations (0.035% and 5%) were assessed during 56 d of storage at 0.5 °C. The 5% CO 2 atmosphere combined with 21 or 10% O 2 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% CO 2 at all O 2 concentrations. Storage of fruit in 0.035% CO 2 and 21 or 10% O 2 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

How this classification was reachedexpand
Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
