bitter pit susceptible varieties. 



In order to be sure scald is not developing on such varieties as Cortland, 

 R, I. Greening, Rome Beauty and Mcintosh, it is necessary to place apples at 

 room temperature for several days. The placement of the samples in unsealed 

 polyethylene bags is suggested. Apples may show no scald in storage but with- 

 in several days at room temperature have 100 per cent scald. In case of 

 regular storage Mcintosh, the immature fruits usually scald worse. The opposite 

 is true with Mcintosh in CA storage. 



internal breakdown which in some years follows water core in Delicious 

 apples and strains of the variety may be a problem during the 1960-61 storage 

 season. The following table shows the amount of and severity of water core 

 present in Starking and Richared Delicious apples on September 29, October 10 

 and 20, 1960 in the University orchard. 



TABLE I - WATER CORE IN STARKING AND RICHARED DELICIOUS APPLES AT HARVEST 



Because of the limited number of trees, etc., the data in the table are 

 insufficient to draw any conclusion as to any difference in Delicious strains 

 and their susceptibility to water core. 



However, the data presented in the table show the necessity of examining 

 various lots of apples from different trees In the orchard to get an accurate 

 picture of the water core situation.
