Abstract

オオバコの種内変異を調査するため, 京都市北東部の8集団かち得た系統を供試し, 同一条件下での栽培実験を行なった。さらに, 生育地の環境を調査して, 種内変異と生態分布との関連を検討した。1) オオバコの形態には著しい遺伝的変異が認められ, 普通型と minima 型の2型が識別された。普通型では, 葉は大きく斜立し, 葉脈数は5で, 花序は長く, 斜立~直立し, 1蓋果は3~7個の大きな種子を結ぶ。minima 型では, 葉は小さく傾伏し, 葉脈数は3で, 花序は短く, 傾上し, 1蓋果は4~10個の小さな種子を結ぶ。2) 普通型は, 畦畔や農道, 路傍, 未舗装の駐車場, 社寺林の林床などに生育していた。minima 型は神社や仏閣の境内に限って生育していた。3) minima 型の生育地である神社の境内は, 薄暗く, 土壌中の窒素とリンの含量が普通型の生育地より低く, 維管束植物の多様度指数が低く, また毎日掃き掃除が行われるなど, 普通型の生育地とは環境条件や管理様式が顕著に異なっていた。そのため, minima 型はストレスや撹乱の質と程度に関して普通型とは異なった環境に生育していると考えられた。オオバコの種内2型はこのような生育地の環境条件の違いに適応し, 住み分けているものと推定された。
