CHEJ'IICAL THINNING OF APPLES 



Vfe are in the midst (May 11) of an extremely favorable blossoming period, 

 perhaps the best one in the past h or 5 years. Since many of our luclntosh trees, 

 particularly in the eastern part of the state, have a very heavy bloom, the chances 

 of an overset and biennial bearing of this variety is a real possibility of chemical 

 thinning Hclntosh, the data in Table 1 may be of interest. These trees are in the 

 University Orchard at Amlierst.

 calyx on the set, size, and yield in 1952 and the extent of
