years of age or less, however, Mcintosh outnumbered Delicious (regular 

 and red strains) by only a 2-to-l margin. 



Golden Delicious will become more important in the future since 

 over 60% of the trees on standard root stock of this variety are 7 years 

 of age or less. 



Spur-type trees and trees on size-controlling rootstocks made up 

 about 8% of all apple trees recorded in the 1963 survey, but of the trees 

 7 years of age or less, nearly half were of these types. 



The number of spur-type Red Delicious trees and trees of this varie- 

 ty on Mailing II and VII rootstock were approximately equal. Spur-type 

 Red Delicious and those of this variety on size -controlling rootstocks 

 outnumbered Mcintosh on size -controlling rootstocks 8172 to 4-880.

Winter injury may be more of a problem in strawberry growing than 

 is generally realized. Vermont horticultural researchers have found 

 that strawberries can be injured by a temperature of 28 F, resulting in 

 smaller plants and reduced yields. Plants are killed at temperatures 

 between 15° and 20°F. 



The kind of weather conditions to which plants are exposed influences 

 the severity of injury. It was found that injury increased as the rapid- 

 ity of freezing increased. By the same token, injury increased as the 

 rate of thawing increased. And the longer the period of exposure to low 

 temperature, the more severe the injury. 



Snow was found to be the best cover for protecting plants from win- 

 ter injury. A snow fence consisting of a row of sunflowers grown 6 

 inches apart increased the snow cover to the extent that the strawberry 

 bed was still snow-covered after a January thaw while the surrounding 

 ground was bare. The seed heads were cut off the sunflowers to prevent 

 breakage. A spacing of 8 rows of strawberries between rows of sunflowers 

 is recommended.
