Abstract

In this study we investigated the relationship between characteristics of vegetative growth of three species of Viola (V. rossii, V. japonica, and V. dissecta var. chaerophylloides) and light in order to explain how these three species could live together under a closed space in a forest. This studywas carried out at five sites in Mudeung-san (Mt.) on 1994, 1995, and 2000 and additional investigations were performed on 2007 and 2010 at the same sites. In order to find the relationship, three main investigations were conducted: counting number of individuals for each investigated year, measuring dry mass and counting developed leaves per plant, and finding presenting patterns of each species with reference to incidence of light. As a result, we found that three species could share the closed space in a forest because of their different adaptive strategies like V. rossii as Kstrategist, V. japonica as r-strategist, and V. dissecta var. chaerophylloides as an intermediator between two species.

임상의 동일 공간에 생육하고 있는 제비꽃속 세 종(고깔제비꽃, 왜제비꽃, 남산제비꽃)의 영양생장적 특징과 광량의 관계를 통해 각 종의 전략자적 특징을 알아보았다. 본 연구는 광주광역시에 위치한 무등산의 다섯개 지점으로부터 1994년, 1995년, 2000년에 중점 조사가 수행되었고, 2007년과 2010년 추가 조사가 진행되었다. 각 종의 집단 내 개체수의 변동, 개체의 건중량과 엽수, 조도에 따른 종의 분포 유형 분석을 통해 세 종이 임상의 광양에 의해 서로 다른 생태적 지위를 얻고 있음을 알 수 있었다. 고깔제비꽃은 K-전략자로서, 왜제비꽃은 r-전략자로서, 남산제비꽃은 두 종의 중간에서 그 생태적 지위를 차지하는 것으로 해석되었다.
