HEAD FORMATION IN APPLE TREES

Plate VIII. Mcintosh Tree H46, at seven years. 



Follow the development of the branch shown on the right in 1. In Plate VII this 

 has developed strongly and suppressed branches above. It should have been cut back 

 severely or removed the first year. Note the suppression of the leader in 3a. Prob- 

 ably it should have been checked sooner, as that would have prevented the heavy 

 growth of the upper branches shown in Plate VIII. These strong branches shade and 

 thus check the lower branches. Total yield 473 pounds.
