winter Injury 



The results of H. A. Rollins, Jr. and et al published In Ohio Agricultural 

 Experiment Research Bulletin 901 show that for a short period after apple trees 

 are heavily pruned, the cold resistance of the trees is reduced. They suggest 

 that prior to January, growers should avoid pruning the more tender apple varieties 

 if severe low temperatures are predicted within a few days. 



The findings of H. A. Rollins, Jr. and et al substantiate the observations 

 of growers who have noted winter injury to apple trees pruned just prior to a 

 period of sub-zero temperatures.

RESEARCH FROM OTHER AREAS 



The results of a fruit tree survey conducted in New York was discussed by 

 B. A. Dominick in the November 1962 issue of the New York State Horticultural 

 Newsletter. Surveys of this type are of value in determining the future trends 

 of the fruit industry. Because the varieties grown in New York are similar to 

 those in our Massachusetts orchards, the information taken from B. A. Dominick's 

 article is of particular interest. 



It can be noted below that in western New York, Monroe and Idared account 

 for 7 and 6 per cent respectively of the total non-bearing trees. Idared has 

 been recommended for trial in Massachusetts for the last several years. The 

 Monroe variety was discussed in the January 1963 issue of Fruit Notes by 

 Dr. W. D. Weeks in the article titled "Notes on New Apple Varieties". This 

 variety was introduced primarily as a processing apple but has good dessert 

 qualities. Dr. W. D. Weeks is of the opinion that where a dual-purpose variety 

 is desired, Monroe appears worthy of trial. 



Apple Varieties in Eastern N. Y. 



"While recent plantings of young apple trees in both sections of the State 

 have been at rates high enough to maintain bearing tree numbers, the percentages 

 vary widely between different varieties in both areas. Included in the tables for 

 Eastern and Western New York are each variety of apples amounting to at leant one 

 per cent or more of trees under eight years of age or those eight years old or 

 older. In Eastern New York, Mcintosh is the leading variety among bearing trees 

 accounting for 42 per cent of the total (table 2). This variety accounts for 

 only 27 per cent of the total non-bearing trees of all varieties. Only 16 per 

 cent of the Mcintosh trees are non-bearing, while the estimated percentage 

 necessary to maintain the number of bearing Mcintosh trees is estimated to be 

 18. Among the five leading varieties, Delicious promises to be more important 

 in the area in the future with 39 per cent of all the non-bearing trees. Followed 

 by Mcintosh, the next most important variety in young plantings is Golden Delicious 

 with 10 per cent of the total. Rome follows Golden Delicious with eight per cent. 

 No other variety accounts for as much as four per cent of the total young trees.
