Frost Injuries and Protection, Secondary Bloom 331 



In the apple we have three types of second-crop bloom. 

 One common abnormal type of bloom is that springing 

 from the axil of a leaf on a normal spur after the early 

 bloom has been killed by frost. This bloom will set and 

 mature fruit, provided the ripening season of the variety 

 is well within the season of the particular locality; fruit 

 from such bloom is 

 usually later and re- 

 quires an extension 

 of the season in 

 which to 'develop. 

 Figure 92 shows a 

 mature Chenango 

 (Strawberry) apple 

 from such bloom, 

 not over a week 

 later in maturing 

 than that from 

 normal bloom. As 

 the fruit generally 

 develops within a 

 week after that 

 from the earlier bloom, in our lower altitudes most varieties 

 will mature a crop from all late bloom. 



Small-fruits set from a second type of late bloom, shown 

 in Figure 93, which is a fruit-spur forced from the larger 

 limbs and even from the trunk. While such bloom often 

 occurs in normal years, the amount is apparently multi- 

 plied by the destruction of the earlier bloom. This type of 

 late bloom seems to terminate growth that should normally 

 havebeenawatersprout; in fact, the growth shown in the

 crop Bloom.
