Research Abstract

日本と北米大陸に現在隔離分する広義のユリ科植物の中でも、日本の近縁種に関して、これまで詳細な生活史研究が行われてきた生態的背景がわかっている種群を対象に、繁殖様式ならびに個体群構造に関する、詳細な野外調査と分子マーカーを活用した遺伝解析を行った。その結果、さまざまな種群について有益なデータを得ることが出来た。特に、カタクリ属(Erythronium)、スズラン属(Convallaria)、バイケイソウ属(Veratrum)に関しては、繁殖特性に関わる集団間ならびに集団内の他殖率の変異性、および個体群統計遺伝学の側面から、種子繁殖と栄養繁殖の寄与に関して、環境と生活史形質の変異の関係を明らかにすることが出来た。
