説明
INOUE, Ken (Bot. Gard., Fac. Sci., Univ. Tokyo, Tokyo). 1985. Reproductive biology of two Platantherans (Orchidaceae) in the island of Hachijo. Jap. J. Ecol., 35 : 77-83. Capsule sets of Platanthera okuboi (abbreviated as okuboi) and P. mandarinorum ssp. hachijoensis (hachijoensis) on Hachijo Isl. and factors affecting them were investigated. Average percentages of capsule set of hachijoensis at two study sites were both over 90%, while those of okuboi were much lower and 20-30%. From patterns of capsule formation and the number of trapped pollinaria-bearing moths, okuboi was estimated to be pollinator-limited, and hachijoensis unlimited. In okuboi, the decrease of pollination and increase of predation were observed in a closed habitat, and larger spikes were more effectively pollinated than smaller ones. In hachijoensis, nearly all the flowers were pollinated regardless of habitats and spike size, and the level of predation was low and unchanged in different habitats. It was pointed out that the two Platantherans are under different evolutionary dynamics.
