| 摘 要： | 用淀粉凝胶电泳,分析苹果实生苗新梢皮层的过氧化物酶同工酶,其酶9带(A_9)与苹果的矮生习性相关,且不受树龄、苹果类型以及栽培条件等影响。在矮生型苹果育种中,A_9可以作为预选标志,其准确率为86.14%。

| Abstract: | Peroxidase isozyme zymograms of the cortex of the shoot of 1 or 2-year-old seedling were obtained by starch gel electrophoresis.In different species,cultivars,and root stocks,the ninth enzyme band(A_9)is positively correlated with spurtype and dwarfing propensity of rootstock. The A_9 is not influenced by seedling age,calture condition,rootstock and interstock.There- fore,it could be used an a marker for preselection of apple seedling for spurtype and dwarfing of rootstock.The accuracy of this method is about 86%. |
