Abstract

This study was about three genus of Viola: V. rossii, V. japonica, and V. dissecta var. chaerophylloides which can live together under a deciduous forest canopy. The aim of the study was to directly compare reproductive characteristics of the three species under the same environmental condition. By taking a census of the morphologically different flowers, the results indicate that all three species opened chasmogamous flowers before the canopy of forest closed, but continuously opened cleistogamous flowers after the canopy closed. Numbers of seeds in a capsule followed an ascending order from V. rossii to V. japonica. Mass of seeds followed a descending order from V. rossii to V. japonica. Both results had statistical significance. In terms of characteristics of seed production, V. rossii has been adapted more than V. japonica, and V. dissecta var. chaerophylloides under the deciduous forest.

본 연구에서는 낙엽수림 지역에 혼재하고 있는 제비꽃 속 중 고깔제비꽃, 왜제비꽃, 남산제비꽃의 생육기간 중 개화 시기와 생식 방법에 따른 종자의 생산량 등을 조사하고 비교 분석하였다. 그 결과 3종 모두 수관이 폐쇄되기 전의 짧은 기간 동안 개화 시기에 미세한 차이를 두고 개방화를 생성하였고, 폐쇄화는 수관이 폐쇄된 이후에도 지속적으로 생성되었다. 삭과 한 개당 종자 수는 고깔제비꽃<남산제비꽃<왜제비꽃 순서였고, 종자 무게는 고깔제비꽃>남산제비꽃>왜제비꽃 순서로 종간과 생식 방법에 따라 유의적으로 차이가 있었다. 세 종의 종자 생산 특성을 비교해보면 고깔제비꽃이 왜제비꽃이나 남산제비꽃보다 본 조사지와 같은 낙엽활엽수림에 적응도가 큰 것으로 생각된다.
