Cion—any plant part, usually of a stem, insertedin a stock for propagation. It may consist of one budwith little or no wood, as in budding, or of one or morebuds with one or more inter-nodes, as in grafting. 196. Objects of graftage. Graftage may be used: 1,To alter plant character by modifying wood, foliage, orfruit produced. 2, To develop branches, flowers or fruitwhere they are lacking on trees or shrubs. 3, To enhance.

Necessity for graftage. Since seedage is quickerand cheaper, graftage is rarely employed to propagatespecies, and then only stich species as produce seed spar-ingly under cultivation are so reproduced. For similarreasons cuttage and layerage are preferred for mostshrubs. Graftage finds its chief a])plication, therefore,in the propagation of varieties and strains of woodyl)lants that do not come true from seeds and that cannotl)e cheaply or conveniently enough grow
