GROWING AND FRUITING HABITS 401 



Group III. — Fruit buds borne terminally, unfolding to produce 

 leafy shoots with flowers or flower clusters in the leaf axils. 



This might be called an incomplete terminal bearing habit, for the 

 fruit itself is not borne terminally, but is lateral to the growths upon which 

 it appears. However, the flower buds are terminal. The terminal buds 

 of the flowering shoots may differentiate flower parts for the following 

 year's production or new buds may develop from lateral leaf buds. 



None of the common deciduous fruits has this bearing habit. It is found in 

 the pomegranate, the tropical ahnond {Terminalia catappa), the guavas {Psidium 

 spp.), the olive, and in a number of the species of Eugenia. In the pomegranate, 

 guava and in the Eugenias the fruit buds are formed on short shoots or spurs 

 and the flowers and fruits in the axils of the outermost leaves. In the oUve the 

 inflorescences are generaUy found in the axils of the shoot's lower leaves and 

 flowering shoots sometimes spring from lateral as well as terminal buds (see Fig. 

 41). The tropical almond {Terminalia) has a somewhat })eculiar growing and 

 fruiting habit, the terminal mixed flower buds being formed on the ends of long 

 shoots. When these unfold they give rise to short growths or spurs, in the axils 

 of whose upper leaves flowers and fruits are borne. The long growths or shoots 

 originate from lateral buds. 



Group IV. — Fruit buds borne laterally, containing flower parts only 

 and giving rise to inflorescences without leaves or if leaves are present 

 they are much reduced in size. 



In the peach, lateral fruit buds are formed on the long shoots (see 

 Fig. 42). Two additional or supernumerary leaves commonly appear 

 at many nodes as the season progresses and fruit buds develop in their 

 axils. The bud in the axil of the original leaf generally remains a leaf 

 bud; rarely it too differentiates flower parts. This whole structure may 

 possibly be considered a much reduced secondary growth. Often only a 

 single extra leaf develops at the node, in which case only one fruit bud 

 forms at that point, that in the axil of the supernumerary leaf. The 

 peach also forms fruit buds on secondary or even on tertiary lateral 

 branches. As a rule when the fruit buds occur on the upper or outer 

 portions of secondary shoots and sometimes on the primary shoots, they 

 are single, being differentiated from the bud in the axil of the single leaf. 

 They are quite likely to be in pairs at the more basal nodes. As already 

 stated, the flower buds of the peach are usuallj^ produced on what would 

 be called long growths or shoots, though under certain cultural and prun- 

 ing treatments many varieties form short laterals that are comparable 

 to spurs in every way. The flower bud of the peach produces only one 

 flower. Growth is continued b}^ terminal or by lateral leaf buds. 



The sweet cherries and the Domestica and Insititia groups of plums 

 form their flower buds for the most part laterally on spurs (see Fig. 

 43). These come from lateral buds on the shoots of the preceding season
