FIG. 46— FRUIT AND 

 LEAF BUDS OF 



PEACH 

 A, end of two-year 

 and beginning of one- 

 year wood. Bud<* 

 largely in threes. The 

 outside ones are fruil 

 buds the ones between 

 leaf buds. B, is con- 

 tinuation of another 

 part of the shoot — an- 

 other third part. Such 

 growths must be cut 

 back severely both to 

 reduce the number of 

 fruits and to prevent 

 the undue extension 

 of the branches from 

 the terminal buds, 

 more particularly. The 

 whole one-year part of 

 the branch in this case 

 is 30 inches long. It 

 is cut in A at 8 inches 

 and in B at 10.

 the tip. Compare Fig. 46,

 PEACH TWIGS THAT 

 HAVE BORNE FRUIT 

 B, note annual growth 

 ring at c^ above which 

 the twig is one year 

 old. C, four years' 

 growth of a so-called 

 spur with annual 

 growths starting at c, 

 d, e. Fruit stems on 

 both twigs at b. Thus 

 the fruits and the 

 growths from e to the 

 tips of branch C were 

 developed simultane- 

 nches long from c to

Japanese plums suggest the apricot in bloom-bearing 

 habit — axillary l)uds on spurs and also on vigorous young 

 wood; in this latter case, like peach bloom buds, in 

 couples, with a branch bud between. During the dormant 

 season the recognition of plum blossom buds is often ex- 

 ceedingly difficult, though in some varieties it is easy.
