Second, it enables one to preserve bvd sports, which are individual branches that show qualities strikingly dif- ferent from other branches of the same plant. Since bud sports rarely take root from cuttings or come true from seed, grafting is usually the only way of preserving them; and so important are bud sports that most of the best varieties of such fruits as Apples, Pears, and Oranges have originated as sports, which, after being grafted on stocks, became trees which by further grafting have been multiplied. Often minor influences of the stock on the cion, such as dwarfing, hastening the fruiting period, or altering the time of blossoming, are desirable, and are obtained by grafting the cion on suitable stocks. For example, Pears are dwarfed and fruit at an earlier age when grafted on the Quince. Apples are influenced in the same way when grafted on the so-caUed " Paradise " stock, a name.
