选育矮生型(短枝型、矮生、矮化苹果新品种是苹果生产上的一个很重要的课题。矮生型品种适宜密植,容易修剪,便于管理,早期丰产性和品质都好等优点。但矮生型苹果的预选技术到目前为止仍是国内外尚未解决的难题。本成果在1979年初,我们观察到过氧化物酶酶谱型与矮化有关。1981—1984年证明了过氧化物酶酶9带能作为预选1—2年生矮化型苹果实生苗的经济有效的指标。
Breeding dwarf type (spur type, dwarf, dwarf apple varieties is an important issue in the production of apples. Dwarf varieties suitable for close planting, easy to trim, easy to manage, early high yield and quality are good However, the pre-selection technique of dwarf apple is by far the unsolved problem at home and abroad.This result was observed in the beginning of 1979. The peroxidase zymotype is related to dwarfing.From 1981 to 1984, Oxidase-9 band can be used as a cost-effective indicator of pre-selected 1-2 year-old dwarf apple seedlings.
