Pomological Paragraph 



15,000 Shopping Centers by 1975 have been predicted by the International 

 Council of Shopping Centers. Just 17 years ago there were only about 50 

 shopping centers in the U.S. The current growth rate sees one center 

 opening every 10 hours each day of the year. By 1970, a mere 2,000 re- 

 tailers may be doing close to i+0% of all retailing. This would leave 

 about 1,200,000 stores to handle the balance of the business. Further, 

 the shopper is changing; the woman shopper today accounts for about 50% 

 of retail expenditures vs^. 85% a few years ago. In about 5 years the 

 American consumer is expected to spend more money on services than on 

 non-durable goods. Self-service will be even more commonplace than today. 

 These retail trends are worthy of note and serious consideration.

The Effect of Type and Season of Pruning on Growth and Yield of Dixigem 

 Peach Trees . 



E. F. Savage, ejt. aJ . , Georgia Experiment Station, Athens, Georgia, 

 report that yields, fruit size, and tree growth were essentially the 

 same on Dixigem peach trees pruned vase-shaped as compared to the modi- 

 fied leader system. (Vase-shape trees are opened center trees with 3 

 or L+ scaffolds rising from the trunk at about the same height. Modified 

 leader pruned trees, which are recommended for Massachusetts, have 3 to 

 5 main scaffold limbs equally distributed around the tree and are at 

 least 6 inches apart vertically.) 



The labor requirement to maintain vase-shaped trees was consider- 

 ably higher since the prunings removed from these trees averaged 33.9 

 per cent heavier than those from modified leader trees.
