The upper figure in Plate VI shows the average condition of a lot 

 of Wagener apples in March, 1903, when removed from storage; the 

 lower figure, the average condition of the same fruit forty-eight hours 

 later in a temperature of 70° F. 



It should be the aim of the fruit s'orer not only to remove the fruit 

 before the scald normall} T appears, but to hold the apples after removal 

 in the lowest possible temperature to prevent its rapid development. 



INFLUENCE ON SCALD OF DELAYING THE STORAGE OF THE FRUIT AFTER 



IT IS PICKED. 



The ripening of the fruit between the time of picking and its storage 

 increases its susceptibility to scald. 



When the picking and shipping seasons are cool and diy it maj T be 

 possible to delay the storage of the fruit for sometime without injury 

 so far as the predisposition to scald is concerned. In the investigations 

 of 1901-2 in western New York there was no apparent injury from 

 delaying the storage, but the weather conditions at this period were 

 ideal for apple handling. 



The scald develops seriously when the storage of the fruit is delayed 

 in hot weather. Detentions in the orchard, in transit in closed cars, 

 in unloading at the terminal, or in the warehouse cause the fruit to 

 ripen quickly and favor the rapid growth of the fruit- rots, as they 

 bring the fruit much nearer the end of its life before it enters the 

 storage room. Under these circumstances the fruit may scald badly, 

 mellow early in the season, and rot, and no storage treatment can cor- 

 rect the abuses to which it has been subjected. 



The following table brings out the injury that may be caused by 

 dekying the storage of the fruit in hot weather. The mean average 

 temperature between September 15 and 30, 1902, was about 62° F. 

 and the mean average humidify about 81 c . Fruit picked from the 

 same trees on October 1, 1902, and stored two weeks later, when the 

 temperature was about 53° F. and the humidity about 80°, was not 

 injured by the delay. The apples referred to were grown in eastern 

 New York and stored in Boston, and these records were taken the 

 following February.
