Research Abstract

The demographic-genetic structures of field populations of five Japanese liliaceous species, i.e., Erythronium japonicum Decne., Fritillaria koidzumiana Ohwi (both typical polycarpic outbreeding perennials), Cardiocrinum cordatum (Thunb.) Makino (incl. var. glehni (Fr. Schm.) Hara) (a monocarpic perennial), Disporum sessile D. Don and Disporum smilacimum A. Gray (both monocarpic pseudo-annuals), were investigated in several localities of Toyama Prefecture, Honshu. For all five species, size-class structures of populations were investigated based on the leaf area of each individual plant present in the unit-sampling plots. Then, peroxydase isozyme patterns of each population were analyzed by the isoelectric focusing method using a thin plate of ampholine. All peroxydase bands which were detected in a pH range of 3.5 to 9.6 of ampholine were analyzed based on the dissimilarity index.
Typical normal curves of the D.I. values were obtained from wild populations of Erythronium japonicum and Fritillaria koidzumiana, whereas a somewhat skewed distribution pattern was detected in those of Cardiocrinum cordatum, which propagates vegetatively by producing daughter bulblets. On the other hand, Disporum smilacinum, a monocarpic pseudo-annual with entirely different population structures, exhibited exceedingly skewed distribution patterns of the D.I values.
All such different demographic-genetic structures of plant populations are most strongly determined by the method of reproduction (whether predominantly amphimictic or apomictic) and by the breeding system (whether predominantly outbreeding or inbreeding) of the particular species in question.
