Not illustrated. 1916 Excerpt: ...both the preservation and the multiplication of valuable kinds of plants which appear as Bud Sports, but which neither transmit their good qualities through seed, nor strike root from cuttings, and hence, except for grafting, would be lost. Bud sports, which are related to monstrosities (page 205), are individual branches which show in their development some striking difference from others on the same plant. Most of our best varieties of Apples, Pears, Oranges, and other fruits, have originated in this way, and are perpetuated only by grafting. Indeed, grafting may be denned from this point of view as a process of fitting a set of ready-made roots upon kinds of plants unable to make any of their own. Second, grafting can be used to produce certain desirable changes in minor qualities of the cion, though no essential features can thus be altered. An earlier or later time of blossoming or fruiting of a tree, a better adjustment to a particular soil or climate, advantageous dwarfing or enlarging, resistance to root parasites, even in some small degree an improvement in color or size may be wrought in the cion by grafting on a suitable stock. All such features, however, seem to depend upon the sap, which of course is supplied by the roots of the stock. The more essential characters are seated in the protoplasm, and remain unaltered by grafting, since the protoplasm, unlike the sap, does not pass from stock to cion, but remains separate in the two. Third, curious effects in plant form are obtainable by grafting, as when a dozen or more varieties of Cherries are made to grow on one tree, or bizarre constructions are produced by the grafting upon one stock of many forms of Cacti, which happen to graft extraordinarily well. The older books upon horticulture frequen...
