摘要: An intra-species comparison of the life history various populations ofPolystichum tripteron was undertaken in Hokkaido and Honshu Japan with respect to some leaf-size characters fertility during sporophyte development. The developmental process sporophytes quantitatively estimated by counting number venation (NV: midrib branches leaf). mean NV fertile leaves decreased slightly increasing altitude on Mt. Teine near Sapporo latitudes from Hokkaido. blade length longer at any than those southern Honshu. Longer (BL) pinna (PL) lesser pinnules lowest (NPLP) versus were observed leaf maximum values (LPL), NV, costa (NVLP) pinnule larger In course leaf-shape formation represented ratio PL BL Kyoto population seemed be more differentiated into long-lanceolate fronds did population. Initiation development decrease altitudes Japan.
