Breakdown : 'Idared' can break down in a manner similar to the 

 problem with late-picked, large 'Jonathan.' Fruit size in relation 

 to breakdown was examined. Large fruit (78 fruit/box) had over 

 60% breakdown after storage, whereas smaller fruit (89-153 fruit/ 

 box) had little or no breakdown. Maturity was also examined, and 

 fruit harvested at the end of October or early November had a much 

 greater susceptibility to breakdown than those picked in mid-October, 

 Limited evidence suggested that the fruit that broke down were low 

 in calcium. Attempts to reduce breakdown with calcium sprays and 

 dips have not succeeded to date.

This trial in grower orchards was such that the data could 

 not be statistically analyzed. Therefore, it is not possible to 

 determine if the 0.9 and/or 0.6 lb firmness difference after stor- 

 age of Alar and check fruits was significant. However, data ob- 

 tained in other experiments in 1971 and 1972 showed that the firm- 

 ness difference of Alar-85* fruits harvested in the first picking 

 persisted in storage whereas it disappeared if the fruits were 

 picked 7 days later (Table 1).
