Effects of delayed controlled atmosphere storage on disorder development in ‘Honeycrisp’ apples
Bibliographic record
Abstract
Abstract: The objective of this study was to investigate the effects of delayed controlled atmosphere (CA) storage on fruit quality and disorders in temperature conditioned ‘Honeycrisp’ apples. For three consecutive years, ‘Honeycrisp’apples were harvested from the same commercial orchard and conditioned for 4 d at 12-19 °C immediately after harvest. Apples were then held in ambient air at 3 °C for 0, 2, 4, 8, or 14 wk, followed by CA storage (3 kPa O2 and 1.5 kPa CO2) at 3 °C for 6 or 7 mo of total storage time. The effect of 1-methylcyclopropene (1-MCP; 1 µL L-1) was also investigated. Delaying the establishment of CA reduced the incidence of internal CO2 injury, with or without flesh cavitation. Furthermore, higher incidence of CO2 injury required longer delay of CA to reduce the disorder. In some years, delayed CA also resulted in increased lenticel breakdown, bitter pit/blotch and greasiness. 1-MCP treatment reduced lenticel breakdown when CA establishment was delayed 4 wk or more. There was variation in fruit firmness among years and durations of CA delay, and some increase in firmness was observed during storage. 1-MCP-treated fruit showed little change in firmness with delayed CA. There was also little effect of delayed CA on internal ethylene concentration (IEC), soluble solids concentration (SSC), and malic acid content. These results suggest that conditioning and delaying CA storage reduces the incidence of internal CO2 injuries in ‘Honeycrisp’ apples, but the delay may aggravate other disorders.

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.
