Abstract

Fruit-discharge type of forty species of Asian Geranium were examined and their evolutionary trends and taxonomic system were discussed. Two main types of seed discharge in Geranium are made the basis of its divison into subgenera: Geranium subgenus Geranium, with a ballistic expulsion of the seed from mericarp, Geranium subgenus Robertium, with forcible discharge of the mericarp with the seed in it, separately from the awn. Variants of the seed ejecting type permit the division of Geranium subgenus Geranium into three sections. Section Ceranium, these has bristles at the base of the mericarp for prevent the seed from dropping from the divergent mericarp. Section Dissect, these has prongs at the base of the mericarp far prevent the seed from dropping from the divergent mericarp. Section Tuberosa, these has no bristles and prongs at the base of the mericarp, instead, retained of seed in pre-explosive interval by twist. Geranium subgenus Robertium was divided into two sections, Section Ruberta, with deeply wrinkled on the surface of mericarp at the time of discharge. Section Batrachioides, and section Trilopha, without wrinkle on the surface of mericarp at the time of discharge. According to the seed discharge, subgenus Geranium is thought to be more advanced than subgenus Robertium.

쥐손이풀속(Genus Geranium) 40분류군에 대하여 종자산포형태에 따른 생식형질을 조사하고, 이들의 분류체계 및 진화경향성을 논의하였다. 종자산포시 분과와 까락이 탄력적으로, 위로 감겨 올라가면서 종자가 산포되는 Geranium아속과 종자산포시 분과와 까락이 완전히 분리되어 종자가 산포되는 Robertium아속으로 구분된다. Geranium아속은 다시 종자를 일시적으로 유지해 주는 분과의 부속체기저부에 강모가 있는 Geranium절, 포크형태와 같은 갈고리 모양의 Dissect절. 강모나 갈고리형의 부속 체를 가지고 있지 않지만 분과가 비틀어지면서 종자를 유지해 주는 Tuberosa절로 분류되어진다. Robertium아속은 종자산포시 종자가 까락과 중심주로부터 모두 분리되면서 분과의 표벽이 심하게 주름이 지는 Ruberta절과 분과의 표벽에 주름이 없는 Batrachioides절과 Triloph절로 나어진다. 종자산포방식에 따르면 Geranium아속이 Robertium 아속보다 더 진화한 분류균으로 생각된다.
