TERMS DEFINED 



THE term graftage is now accepted to include both grafting and 

 budding. The real difference between these two processes 

 is slight. Budding is inserting a single bud into the growing wood 

 of a plant; grafting consists of using a twig bearing several buds 

 instead of a single bud. Also included under graftage is the process 

 of inarching, or grafting by approach. 



The term don (often spelled scion) is used to designate the por- 

 tion of one plant which is inserted upon another plant, called the 

 stock. The stock is usually rooted so that it may gather the nour- 

 ishment from the soil and furnish it to the cion. 



It must be remembered that even though the stock and cion 

 are in intimate union, each retains its own individuality. The 

 bark and wood tissues of the two never mix, but merely knit to- 

 gether. 



Most dicotyledonous plants, as Apples, Legumes, Cacti, Com- 

 posites, Crucifers and members of the Potato family, have been 

 grafted. Monocotyledonous plants, as Lilies, orchids, Grasses, 

 Irises, and the Aroids, have never been grafted for commercial 

 purposes, because their parts are not adapted for the essential close 

 union. Evergreens are also grafted.
