通过对中国东北(内蒙、吉林、辽宁)生长的西伯利亚杏(Prunus sibirica L.)的形态,染色体,同工酶的研究,将西伯利亚杏划为五个类型:即有毛大果苦果类型,有毛小果苦果类型,有毛果实不苦类型,无毛小果苦果类型及无毛大果苦果类型。并认为前三个为毛杏的变异,后两个类型为原变种的变异,最后提出了同工酶酶谱的定量分析方法 Through the study on the morphology, chromosomes and isoenzymes of Prunus sibirica L. grown in northeastern China (Inner Mongolia, Jilin and Liaoning), Siberian apricots are classified into five types: Mao Xiao fruit bitter fruit type, hairy fruit is not bitter type, hairless small fruit bitter type and hairless fruit bitter type. And considered the first three as the variation of the apricot, the latter two types of variation of the original variant, and finally proposed the quantitative analysis of isozymes
