An electrophoretic comparison of 29 nuclear-coded enzymes was carried out for 21 Cucumis species, and a phylogeny based on pairwise measurements of the respective genetic distances was computed. This phylogeny was compared to the one based on chlDNA cariation (Perl-Treves and Galun 1985). The two phylogenies were found to share the main dendrogram features; they also agree well with most taxonomic data available on Cucumis. Accordingly, most of the African Cucumis species form a close group ("Anguria group" - "Group A"), which is distant from the melon (C. melo), and from a few other distinct species, all of which are far apart from each other. The cucumber (C. sativus) is the most distant species within the genus. Some specific taxonomic implications as well as some general evolutionary problems related to such a parallel investigation of the nuclear genome and the plastome are evaluated.
对 21 种黄瓜属植物的 29 种核编码酶进行电泳比较，并根据各自遗传距离的成对测量计算出基于亲缘关系的系统发育。将该系统发育与基于chlDNA 变异的系统发育（Perl-Treves 和 Galun 1985）进行比较。发现这两个系统发育具有主要的系统发育特征；它们也与黄瓜属的大多数现有分类学数据吻合。因此，大多数非洲黄瓜属物种形成一个紧密的群体（“安古里亚组” - “A 组”），与甜瓜（C. melo）和其他一些不同的物种远离，它们彼此之间相距很远。黄瓜（C. sativus）是属内最遥远的物种。评估了一些具体的分类学意义以及与核基因组和质体平行研究相关的一些一般进化问题。
