Table I. — Effect of maturity of fruit upon susceptibility to apple-scald 



Scald prevention on eastern-grown fruit is apparently not as readily 

 accomplished. In an earlier report ^ the writers found little contrast in 

 susceptibility to scald on eastern Grimes apples, a part of which were 

 picked on August 11, when the fruit was quite green, a part August 28, 

 when the apples were in condition for commercial picking, and a part on 

 September 21, when the fruit was quite yellow. This experiment was 

 repeated in 1917 on Grimes apples from Vienna, Virginia. The first 

 picking was made on August 2 1 , when the ground color of the fruit was 

 green, and a second picking on September 14, when the apples were 

 becoming yellow and were at their best for commercial picking. The 

 fruit was stored in moist chambers at various temperatures ^ in special 

 storage boxes at Washington, D. C, and notes taken at various times on 

 the development of scald. The results are given in figure i.
