PREDICTING STORAGE SCALD POTENTIAL OF 'DELICIOUS' APPLES |

| Abstract:
Analysis of large databases often helps to suggest trends which might provide direction for future research. Data gathered from 'Oregon Spur Delicious' orchards during the period from 1982–1988 were analyzed to identify relationships between pre-harvest factors and the occurrence of scald after long-term commercial CA storage. Regression analysis of the data showed little correlation between any of the fruit maturity indices and the occurrence of storage scald. Cumulative hours (ambient air temperature) less than 10C, Julian date, and days from full bloom correlated with scald with correlation coefficients of 0.50, 0.49, and 0.42 respectively. From these data, it appears the occurrence of scald on fruit out of storage is fairly high until at least 100 hours of ambient air temperature below 10C have accumulated. | |
