Frost Injuries and Protection, Secondary Bloom 333 



rence under our conditions. As these buds open a trifle 

 later than terminal buds and, as the development of the 

 flowers and fruit from them seems to be augmented by 

 the destruction of the early bloom, they may be classed 

 as second-crop bloom. Many of these buds produce fruit 

 when all the bloom from normal terminal buds is killed. 

 The production of fruit from axillary buds, however, is 

 not limited to years when other bloom is killed. Many 

 of our most productive varieties bear this way annually. 

 Figure 12 shows a Jonathan twig of two seasons' growth 

 bearing seven fancy apples on wood of the previous sea- 

 son's growth, or from axillary fruit-buds. This branch 

 was taken from a twelve-year-old tree bearing approxi- 

 mately two boxes of fruit, all from either this type of 

 bloom or from the type of secondary bloom as the fruit 

 shown in Figure 92 has developed from. 



In the pear there is one type of late bloom, that arising 

 from the side of normal spurs. Figure 89 pictures a spur 

 of the Bartlett pear bearing a fruit from a normal bloom 

 and two from these late blooms (two fruits below). A 

 close examination of the larger fruit will show a puckering 

 about the calyx, an indication that the fruit has been in- 

 jured by frost. The figure shows what can be expected 

 from such bloom. Fruit from second-crop bloom will 

 mature, but, while of normal flavor, such bloom cannot be 

 depended on for fancy fruit. It is nearly always rough 

 and irregular. As with the apples, some varieties of pear 

 throw axillary bloom that is a few days later; but the de- 

 velopment does not depend on the destruction of the 

 earlier bloom. Other types of late bloom have not been 

 observed in the pear. Unless plentiful late bloom in the
