作为梨的矮化砧木(在苏联)曾试验和推广过普通榅桲,米丘林北方榅桲,日本榅桲,各种山楂的变种以及花楸洋山楂、唐棣、胡颓叶梨等等。普通榅桲(Cydconia oblonga Mill., C. Vulgaris Pers.)树体矮小或灌木,具白色或淡红色花,但花不丰裕而大,果实甚芳香。很早被利用作为矮化砧木。梨嫁接在榅桲上,比嫁接在野生梨上生长矮小得多,但进入结果期显著提前,同时产生的果实具较优良的品质。米丘林关于利用榅桲作为砧木曾写述如下:“众所周知,某些梨的栽培品种,嫁接在榅桲上发育良好,所得果实的品质较以梨为砧木更 As pear dwarf rootstock (in the Soviet Union) has tested and promoted the common 榅 桲, Beech mulberry northern 榅 桲, Japanese 榅 桲, all kinds of hawthorn varieties and Chinese yam hawthorn, . Common 榅 桲 (Cydconia oblonga Mill., C. Vulgaris Pers.) Tree dwarf or shrub with white or pink flowers, but the flower is not rich and large, the fruit is very aromatic. Very early been used as dwarfing stock. Pear grafted on 榅 桲, much shorter than the grafted on wild pear growth, but significantly advanced into the results period, while the resulting fruit with better quality. Michurin on the use of 榅 桲 as rootstock has written as follows: "As we all know, some pear cultivars, grafted on the 发 发 developed well, the quality of the resulting fruit than pears are more rootstocks
