HABITS OF GROWTH

sections of wood (or one-year spurs) even while the trees are 

 young (Fig. 73) . 



Older bearing trees of practically all varieties, at least in 

 Eastern fruit regions, bear on two-year-old sections of wood 

 (one-year-old fruit spurs) in the heavy-crop year, but not in 

 the light-crop year. 



Many varieties of apples such as York Imperial, Winesap, 



Fig. 73. Young bearing trees of Oldenburg (left) and Wealthy (right). 

 Note that spurs of all ages including the one-year-old spurs are blossom- 

 ing. The lateral buds on the one-year-old shoots and the terminal buds 

 are also blossoming. Biennial bearing trees as York Imperial and Bald- 

 win usually blossom in this same way in the heavy-crop year. 



Arkansas, Baldwin, Wagener, and Stayman Winesap often 

 form terminal and lateral fruit buds in the year when the trees 

 have practically no crop. Such buds blossom the following 

 year when the whole tree is blossoming heavily, but often do 

 not set fruit, especially on the lateral buds, unless the blos- 

 soms on the spurs fail to set. These same varieties, however, 

 seldom form terminal and lateral fruit buds to any extent in 

 the crop year.
