Résumé :
|
Chlorophyll fluorescence (Fv) of Delicious apples at harvest was evaluated as an indicator of superficial scald development during storage. The Fv of 'Imperial' and 'Sturdeespur' Delicious apples was determined at three weekly harvest intervals, and the apples were later evaluated for scald intensity after 2, 4 and 6 months of storage at 0 degrees C. 'Sturdeespur' apples had an overall higher incidence of scald than 'Imperial' apples. Fv at harvest was found to correlate positively with scald development in 'Sturdeespur' apples from Harvest 1. 'Sturdeespur' apples with low Fv (18) were most likely to develop severe scald. However, no such relationship was observed for 'Imperial' apples, or for some 'sturdeespur' apples from harvests 2 and 3. The results of this study suggest that Fv at harvest may be a predictor of scald development.
