Sub-dlvlding this last group we could have: 



This might best be done by having the people who buy apples 

 WELL SATISFIED WITH EACH PURCHASE. 



This may be particularly important in a year of higher prices. 

 Otherwise, a big crop could be made out of a little one.

WATER CORE STUDIES ON RED DELICIOUS APPLES 



During the fall and winter of 1958-59, Dr. F. W. Southwick and the writer 

 studied the Effect of Delayed Picking and Storage on the Occurrence of Water Core 

 and Internal Breakdown in Starking Delicious Apples. The results of the study 

 showed that delayed storage periods of 24 to 92 hours is no cure for water core 

 and internal breakdown and that water core severity appears to be closely related 

 to fruit maturity. Although, approximately 42 per cent of the Starking Delicious 

 apples examined had water core at harvest on October 10, 1958, it practically 

 disappeared by the end of the storage period. However, fruits harvested on 

 October 20 and 30 had a greater amount and severity of water core and considerable 

 amount of internal breakdown was present at the end of the storage period. 



The effect of harvest date on the occurrence and severity of water core in 

 Starking Red Delicious was again studied in 1959-60. To prevent preharvest drop, 

 20 ppm of 2,4,5-TP was applied on September 30, 1959 and fruit samples were ob- 

 tained frcxn the selected trees on three dates - October 1, 15, and 29.
