用同功酶电泳技术识别不同苹果品种效果很好。Menedez等〈1986〉和Weller、Costante〈1986〉报道了采用聚丙烯酰胺凝胶电泳技术,通过同功酶图谱识别苹果砧木。在我们的研究中,采用水平淀粉凝胶测定同功酶,这种方法在识别苹果砧木中尚未使用过。首先,从品种圃中选择13种苹果砧木,在12月采集小枝,并在几天内取其树皮进行分析。剥下树皮从软组织部分取样大约50毫克, Using the same enzyme electrophoresis technology to identify different apple varieties works well. Menedez et al. <1986> and Weller, Costante <1986> reported the identification of apple rootstocks by isozyme mapping using polyacrylamide gel electrophoresis. In our study, horizontal starch gels were used to determine isozymes, a method that has not been used in identifying apple rootstocks. First, thirteen apple rootstocks were selected from variety nurseries, twigs were harvested in December, and bark was taken for analysis within a few days. Peel off the bark from the soft tissue section and sample about 50 mg,
