POMOLOGY 



veals a "secondary" growth arising from the axil of one or 

 more of the leaves. This secondary growth may develop into 

 a shoot of several inches in length or into a spur; generally 

 it is short, often- 

 times merely a 

 bud. Usually it 

 is terminated by 

 a leaf -bud, but 

 if the blossoms 

 fail to "set," a 

 fruit-bud is often 

 formed. In fact, 

 it is by no means 

 rare for a fruit-bud to form 

 on this shoot even though 

 one or more fruits are de- 

 veloping. (See Fig. 3.) 



19. Flower-buds.— A 

 flower-bud is one of the 

 individuals of the flower- 

 cluster, inside or outside of the fruit- 

 bud. 



20. Simple buds. — A simple bud 

 contains either the unexpanded leaves 

 or flowers, but not both. The term 

 usually refers, however, to the fruit- 

 bud. The peach, plum, and cherry have simple buds, but 

 the latter may contain rather prominent leafy bracts also. 



21. Mixed buds. — A mixed bud contains both flowers 

 and leaves; hence it always refers to the fruit-bud. The 

 apple and pear have mixed buds. The fruit-buds of the 

 apple and pear are usually larger, plumper, and less pointed 

 than the leaf-buds, but this is by no means universal. In 

 the Baldwin and many other apples, for example, it is almost

 a single fruit- 

 bud. (Rome.)
