The fruit was placed in humid containers at 74° F and examined for internal break- 

 down, rot, scald, fruit splitting, and brown core at intervals thereafter. The 

 per cent of sound fruit represents that fraction which was entirely free of the 

 above defects. 



From the results shown in Table 1 we see no important benefits in any of the 

 CA modifications tried in comparison to the present standard of 37-38° F with 3 

 per cent oxygen and 3 to 5 per cent carbon dioxide. In fact, use of 32° F instead 

 of 37-38° F (Table 1 - No. 5), even with low carbon dioxide levels merely increased 

 the incidence of brown core. Rapid lowering of oxygen does not appear to be of 

 practical value, either. Obviously, CA storage markedly improved the storage life • 

 of Mcintosh in comparison to regular cold storage fruit in all years.

POMOLOGICAL PARAGRAPHS 



Rapid Cooling of Strawberries 



> The rapid cooling, or precooling, of fruit is not a new practice. It was 

 being tried in the early twenties. Unfortunately, this important part of fruit 

 marketing is often given too little attention. A recent release from California 

 shows that after a rapid cooling to 40° F and a five to six day refrigerated 

 shipping period, their strawberries arrived on Eastern markets with 8 to 21 per 

 cent more marketable berries than those handled without the rapid cooling before 

 shipment. Also, the fast cooling increased their shelf life from four to six 

 days. These berries were placed in the cooler within an hour after picking.

Strawberry Imports and Exports 



Did you know that we import strawberries from Mexico and export to Canada? 

 According to the Foreign Agricultural Service we imported from Mexico 24,576,000 

 pounds of frozen strawberries in 1960, an increase of 10,512,000 pounds over 1959. 

 Imports of fresh strawberries increased from 207,000 pounds in 1959 to 597,000 

 pounds in 1960. In 1959 we exported to Canada 19,300,000 pounds of fresh and 

 5,300,000 pounds of frozen strawberries and during the first nine months of 1960 

 the amounts were 17,780,000 pounds of fresh and 2,052,000 pounds of frozen 

 strawberries.

Semi- Dwarf Trees 



Trees on dwarfing rootstocks are becoming increasingly popular. A local 

 nursery reports that approximately 50 per cent of the trees currently being sold 

 by them in New England are on East Mailing VII roots tock. Trees on E.M. VII
