摘要:

为探讨球药隔重楼(Paris fargesii Franch.)种下分类构成,综合形态特征、物候期、植物化学、分子生物学和地理分布的证据,对球药隔重楼各类群进行对比分析。结果表明:球药隔重楼种下存在5个分类群,分别为球药隔重楼原变种(P. fargesii var. fargesii)、宽瓣球药隔重楼(P. fargesii var. latipetala)、短瓣球药隔重楼(P. fargesii var. brevipetalata)、大萼球药隔重楼(P. fargesii var. macrosepala)和球药隔黑斑种群,它们皆在植物形态、物候期、甾体皂苷构成和ITS序列上有一定差异,并且具有各自的地理分布范围。具柄重楼(P. fargesii var. petiolata)的物候期和甾体皂苷成分更接近于金线重楼(P. delavayi),在ITS系统发育树中聚为一支,并且二者之间存在过渡类群,故具柄重楼应移出球药隔重楼种下,作为金线重楼变种,拉丁学名为Paris delavayi var. petiolata。推测球药隔重楼种内演化顺序为短瓣球药隔重楼→宽瓣球药隔重楼→球药隔重楼原变种→大萼球药隔重楼、球药隔黑斑种群。

Abstract:

In order to explore the taxonomic composition of Paris fargesii Franch., the morphological characteristics, phenological period, phytochemistry, molecular biology and geographical distribution of P. fargesii Franch. were compared and analyzed respectively. The results showed that there were five taxa, including P. fargesii var. fargesii, P. fargesii var. latipetala, P. fargesii var. brevipetalata, P. fargesii var. macrosepala and the black patch population. All of them differed in morphology, phenological period, steroidal saponins composition and ITS sequence, and had their own geographical distribution range. The phenological period and chemical composition of P. fargesii var. petiolata were closer to P. delavayi, and clustered into one branch in the ITS phylogenetic tree, and there was a transitional group between them. Therefore, P. fargesii var. petiolata should be removed from P. fargesiias a variety of P. delavayi, which scientific name was P. delavayi var. petiolata. It was speculated that the infraspecific evolution order of P. fargesii was P. fargesii var. brevipetalataP. fargesii var. latipetalaP. fargesii var. fargesiiP. fargesii var. macrosepala, black patch population.

Key words: Paris fargesii, infraspecific taxonomy, Paris fargesii var. petiolata, Paris delavayi
