| 内容記述 | Development and seasonal changes in dry matter allocation of sporophyte of an endangered species Ophioglos-sum namegatae M. Nishida et Kurita（Pteridophyte ; Ophioglossaceae）distributed in the Watarase Retarding Basin, Tochigi Prefecture, Japan were investigated comparing with closely related allies O. petiolatum.The sporophyll of O. namegatae dispersed spores at mid-May and died back in the end of June when Phragmites clump canopy completely closed. These events in O. namegatae were 0.5 month and 2 months earlier than in O. petiolatum, respectively. Changes in dry matter allocation coincided with these events. A canopy removal experi-ment clarified early die-back of above ground organs of O. namegatae was not concerned with reduction of rela-tive light intensity caused by canopy development of Phragmites communis population. Development of above-ground parts of O. namegatae was affected by daily maximum atmospheric temperature, while rhizome and root were contrastively correlated with daily minimum of subterranean temperature. Total individual numbers dis-tributed in the Watarase Retarding Basin was estimated as 2,811,600, assuming on（1）total habitat area was es-timated as 66 ha,（2）mean number of local populations in 25 m×25 m quadrat was 39, and（3）one clone consisted of two ramets. | |||||
