Tree Age 
Tree age as it might affect the storage life of apples was reported on 
by Stevenson in 1957 (57) and again in 1961 by Stevenson and Watkins (58). In 
the latter paper these authors reported that the age of the tree did not have 
any consistent effects on the incidence of storage disorders in the fruit.
