芦笋是重要的园艺植物。芦笋属包括一些观赏种和一些重要的药用种，分布在旧大陆的旱地上。为了阐明该属植物的系统发育关系，我们比较了10种植物的叶绿体dna （ctdna）限制性位点。答:cochinchinensis。野田螺、天冬螺、镰形田螺、马氏田螺、羽状田螺、scandens田螺、virgatus田螺和sprengeri田螺。该属内的系统发育关系来源于ctDNA限制位点，产生的种间差异值（100 × p）在0.4至2.4之间。与玉米（0.0 ~ 0.3）和小麦（0.24 ~ 1.0）等其他类群相比，芦笋的ctDNA变异程度更高。系统发育树显示，本研究的芦笋可分为两个类群。从ctDNA变异中得出的系统发育关系与Bailey（1944）和Clifford和Conran（1987）提出的略有不同。falcatus（四倍体，2n=40）和A. sprengeri（六倍体，2n=60）的ctDNAS具有相同的限制性模式，表明这两个物种的亲缘关系非常近。此外，将多倍体芦笋类群归为一类也很有意义。芦笋的雌雄异株种（a . ofncinalis、a . schoberioides和a . cochinchinensis）也被归为一个聚类，这表明芦笋的雌雄异株可能是单系起源。
Asparagus officinalis is important horticultural species. Genus Asparagus includes some ornamental species and some medicinally important species, and distributed on dry land in the Old World. To clarify the phylogenetic relationships within this genus, we compared the restriction sites of chloroplast DNAs(ctDNAs)among ten species: A. officinalis. A. cochinchinensis. A. schoberioides, A. asparagoides, A. falcatus, A. macowanii, A. plumosus, A. scandens, A. virgatus and A. sprengeri. Phylogenetic relationships within this genus, derived from the ctDNA restriction sites, yielded values for inter-specific divergence (100 × p) that ranged from 0.4 to 2.4. Compared to other groups, such as Zea (0.0 to 0.3) and Aegilops /Triticum (0.24 to 1.0), the species of Asparagus exhibited higher levels of variation in their ctDNA. A phylogenetic tree showed that the Asparagus species used in this study could be divided into two clusters. The phylogenetic relationships derived from variations in the ctDNA were slightly different from those proposed by Bailey(1944) and Clifford and Conran(1987). The ctDNAS of A. falcatus (tetraploid, 2n=40) and A. sprengeri(hexaploid, 2n=60)gave the same restriction pattern, indicating that these species are very closely related. Moreover, it is of considerable interest that the polyploid species of Asparagus were grouped in one cluster. The three dioecious species, A. ofncinalis, A. schoberioides and A. cochinchinensis, were also grouped into one cluster, which suggests the possibility that dioecy in Asparagus might have had a monophyletic origin.
