초록

우리나라 계방산, 덕유산, 지리산에 분포하고 있는 가문비나무 집단의 보존과 복원 전략 개발에 요구되는 생육 환경을 구명하기 위하여, 가문비나무 침엽의 수명, 침엽 내 엽록소 및 질소 배분 양상을 조사하였다. 가문비나무의 평균 침엽 생존율은 계방산(87.%)이 가장 높았고, 지리산(71.6%)이 가장 낮았으며, 침엽의 생존율은 침엽 연령 증가와 함께 감소하였다. 덕유산과 지리산 가문비나무의 침엽은 연령이 증가함에 따라 엽록소 a, b 모두 증가하였으나, 계방산 가문비나무의 엽록소 함량은 2년생 침엽에서 가장 높았다. 카로테노이드 함량은 계방산 가문비나무 침엽에서 가장 높았으며, 침엽의 연령이 증가함에 따라 카로테노이드 함량은 증가하였다. 엽록소 a와 b의 비는 지리산에서 가장 높았고, 계방산에서 가장 낮게 나타났다. 세 집단의 침엽 연령이 증가함에 따라 엽록소와 카로테노이드 함량의 비는 점차 감소하였다. 가문비나무 침엽 내 질소 함량은 덕유산이 1.51%로 가장 높게 나타났으며, 계방산이 1.40% 으로 가장 낮았고, 질소 함량은 침엽 연령이 증가하면서 감소하였다. 엽록소와 질소 함량의 비는 침엽의 연령이 증가함에 따라 증가하였다.

We have investigated needle life span, photosynthetic pigment and nitrogen allocation pattern in the needle of Picea jezoensis in the three populations (Gyebangsan, Deogyusan and Jirisan) to find out growth environmental condition which needs the strategy development of conservation and restoration against population decline. Needle survival rate was the highest in Gyebangsan (87.0%) and the lowest in Jirisan (71.6%), and it decreased with the increase of needle age. Needle chlorophyll a and b in Deogyusan and Jirisan showed higher content in older needle, but chlorophyll content in Gyebangsan was the highest in 2-year-old needle. Carotenoid content was the highest in the needle in Gyebangsan, and it increased along with needle age. Chlorophyll a/b ratio showed the highest value in Jirisan and the lowest value in Gyebangsan. Chlorophyll/carotenoid ratio decreased with needle age, Needle nitrogen content was the highest in Deogyusan (1.51%) and the lowest in Gyebangsan (1.40%), and the older needle had the lower content. In contrast, the highest chlorophyll/nitrogen ratio represented the oldest needle.
