PO同工酶在植物不同部位和不同时期变化的特性虽然为研究细胞发育和分化提供了一个很好的生化指标,但这种变化对从生化角度进行分类和遗传特性的研究无疑会带来困难。为了弄清苹果植株中PO同工酶谱相对稳定的部位和时期,为利用同工酶进行苹果品种分类、种质特性和遗传研究提供
Although the characteristics of PO isoenzymes in different parts of plants and in different periods of time provide a good biochemical index for the study of cell development and differentiation, this change undoubtedly poses difficulties in biochemical classification and genetic studies . In order to clarify the relative stable parts and period of PO isozymes in apple plants, in order to use isozyme to classify apple varieties, germplasm characteristics and genetic studies
