STORAGE OF FRUIT 365 



Greene * found a considerable variation in the value of 

 wrappers but states that they will extend the cold storage 

 season from two weeks to several months, according to 

 variety of fruit. He concludes, however, that they "are out 

 of the question excepting where apples are packed in boxes 

 or where packed for special purposes in barrels." Much 

 the same results are recorded in a later report on this 

 experiment.- 



331. Influence of cultural conditions. — It is well known 

 to those who grow, store, and sell fruit that any given variety 

 will vary somewhat in its keeping quality, depending on 

 where it is grown and on the particular season. Apple 

 buyers become very discriminating after they are acquainted 

 with fruit districts. Fruit raised on young trees, on low 

 land, and on very light soils is likely to have a poorer keeping 

 quality than fruit grown under the opposite conditions. 

 However, it is difficult to determine the keeping quality of 

 the product from any given orchard except by trial, for no 

 definite rules can be laid down which will have wide ap- 

 plication. 



332. Type of package for storage. — The usual types of 

 package for storage arc the standard apple barrel and the 

 standard bushel box. Other packages are coming into use, 

 such as the paper carton package of varying capacity, the 

 basket and the Boston bushel box. The barrel is used for the 

 great bulk of the apples grown in the eastern United States 

 but it is not entirely satisfactory, for it requires a longer time 

 for the fruit throughout this package to cool than is true with 

 a smaller one. It is not convenient to handle and consider- 

 able bruising occurs incident to proper packing. There is
