경남 진주 도심 교란 지역에 서식하는 초본 식물의 기공 형질 분석

Abstract

As urbanization progresses, many plant communities inhabit disturbed areas in urban areas as patches, and these plant communities, which have a high frequency of non-native plants, interact with and adapt to the urban environment. In this study, we investigated stomatal traits (stomatal density, size and index) of native and non-native non-woody plant species living in disturbed areas in urban areas (Jinju city in Korea). By doing so, we tried to understand patterns of variation of stomatal traits within plant community, and also, to find out why non-native plant species can successfully establish in the area. The result of the present study showed that stomatal density and index of non-native plant species were within the range of those of native plants, and the stomatal size was not different from those of native plants. These suggested that the empty space within ecological niche is not essential for the successful establishment of non-native plants. Stomatal density was correlated with the stomatal index. Among leaf functional traits, only leaf dry matter content (LDMC) was negatively correlated with stomatal size. All plants with kidney-shaped guard cells possessed amphistomatous leaves, and plants with dumbbell-shaped guard cells generally had smaller stomatal density than plants with kidney-shaped guard cells.
