FRUIT -SPURS OF APPLE

scars would have been much larger than they are. 

 It was probably for that very reason, the failure 



of the fruit, 

 that the spurs 

 were able to 

 * throw out leafy 

 shoots nearly 



or quite an inch long, to continue 

 the growth. Yet, even then, no 

 fruit -bud developed on the ends 

 of these spurs, for the small 

 pointed ends clearly indicate leaf- 

 buds. It is seen, therefore, that 

 there may be an alternation in 

 the fruit -spur, even when the 

 spur does not bear fruit. 



To still further elucidate the 

 formation of fruit- buds on the 

 apple, and to recapitulate some 

 of the foregoing observations, let 

 us trace the history of given 

 branches in detail.* 



One of these twigs (Fig. 16)

This account of these three apple twigs is adapted from the author's 

 leaflet entitled "Four Apple Twigs," issued as a nature-study suggestion 

 by the College of Agriculture of the Cornell University, 1890-7. This 

 Icutlot (and also "Lessons with Plants") contains the detailed his- 

 tory of an older and more complicated branch.
