GRAFTING AXD BUDDIXG 327 



in September for apples and pears, budding may 

 be done to best advantage. 



If there is a marked difference in rate of 

 growth of cion and stock, or if for any reason the 

 two do not blend to advantage, an ugly swell- 

 ing often results at the point of union; hence 

 the experienced grower avoids making such 

 combinations. 



These plant affinities cannot be foretold; 

 they can be determined only by experiment. As 

 already pointed out, the success, vitality, and 

 growth of a graft will very largely depend upon 

 the affinity between cion and stock; occasionally 

 species from different genera may be satisfac- 

 torily grafted. 



Some of the pears often thrive even better for 

 a time and produce superior fruit when trans- 

 ferred to a hawthorn or apple stock. Almond 

 cions thrive well on peach or plum seedlings. 

 Apricot cions grow and thrive well on seedling 

 plum or peach stocks. 



Cherrj^ cions do well on seedling stocks of the 

 wild Mazzard cherry of Europe. The Mahaleb 

 cherry is sometimes used when it is desired to 

 have dwarf -growing trees. The peach generally 

 thrives on its own roots only. Apples thrive best 

 on their own roots or on various wild crab apple 

 roots.
