초록

덩굴식물 개머루, 계요등, 까마귀머루, 담쟁이덩굴, 댕댕이덩굴, 인동덩굴, 하늘타리 등 7수종과 덩굴식물이 아닌 쇠뜨기, 쑥 등 2수종을 이용하여 광색소 함량과 SOD활성에 대하여 분석한 결과는 다음과 같다. 100 ppb 처리구에서 볼 때 엽록소 a, 엽록소 b, 총 엽록소 함량, 카로테노이드에서 담쟁이덩굴이 가장 많이 증가하였으며, 엽록소 b와 a의 비에서는 쇠뜨기, 카로테노이드와 총 엽록소의 비에서는 계요 등에서 가장 많이 증가하였다. 덩굴식물과 덩굴식물이 아닌 쇠뜨기, 쑥의 비교에서는 엽록소 b와 엽록소 a의 비에서 확실한 차이를 보였다. 엽록소 a와 b의 비에서보면 엽록소 b보다 엽록소 a가 더 민감한 차이를 보였으며, 수종에서는 담쟁이덩굴, 덩굴식물과 덩굴식물이 아닌 쇠뜨기, 쑥의 비교에서는 덩굴식물이 민감한 것으로 나타났다. SOD 활성에서는 100 ppb 처리구에서 덩굴식물류 7수종과 쇠뜨기, 쑥의 처리전과 처리후의 차이는 쑥에서 3535.7 unit/g로 매우 크게 증가하였으며, 계요 등이 109.3 unit/g로 가장 적게 증가하였고, 개머루 한 수종에서 131.7 unit/g로 감소했다.

This study was analyzed to photosynthetic pigment concentrations and changes of SOD activities on seven species of liana of A. heterophylla, P. scandens, V. thunbergii, P. tricuspidata, C. trilobus, L. japonica and T. kirilowii, and two species of E. arvense and A. princeps of non climbing plants. Concentrations of chlorophyll a and b, total chlorophylls and total carotenoids of P. tricuspidata in 100 ppb ozone site were the most increased. It was the most increased to P. scandens in ratio of chlorophylls and carotenoids, and E. arvense in ratio of chlorophyll a and b. There was difference to ratio of chlorophyll a and b of liana and non liana. At ratio of chlorophyll a and b of 100 ppb ozone site and the control it was more sensitive to chlorophyll a than chlorophyll b, and P. tricuspidata was the most sensitive at comparing with species, and it was more sensitive to liana than non liana. In SOD activities A. princeps was the most increased to 3535.7 unit/g, and P. scandens was the fewest increased to 109.3 unit/g, and A. heterophylla was only decreased to 131.7 unit/g in comparing to 100 ppb ozone sites and the control.
