Contrasting levels of clonal and within-population genetic diversity between the 2 ecologically different herbs Polygonatum stenophyllum and Polygonatum inflatum (Liliaceae).

Abstract excerpt

Comparative studies on clonal and genetic structure between ecologically contrasting congeners may provide valuable insights into the mechanisms promoting the maintenance of genetic diversity in clonal plant species. Polygonatum stenophyllum has long rhizomes (ca. 30-40 cm long) and largely occurs on sandy soils in open river banks, whereas its congener Polygonatum inflatum has short ones (ca. 5-10 cm long) and...
