Abstract

1. Wealthy apples grown in northern Iowa when properly ripened and carefully handled kept well in cold storage until late in February.

2. Apple-scald does not appear to be a factor in the storage of Wealthy apples on well ripened fruit.

3. Soft-scald was most abundant on immature fruit and especially on delayed stored immature fruit. Soft-scald was practically eliminated by immediate storage. This held true with fruit picked in either an immature or in a mature condition.

4. Oiled wraps practically controlled apple-scald on Wealthy and in some cases apparently reduced the amount of soft-scald, but the results with the latter cannot be taken as conclusive.

5. The percentage of Wealthy affected with rots resulting from skin injuries was 11 percent. Approximately seven percent of these rots resulted from mechanical injuries and four percent from growth cracks.
