ABSTRACT
This study investigated effects of water content in leaf, leaf acidity, bark acidity and water soluble sulfur contents by vehicle. The results were as follows: The average water content in Pinus Koraiensis leaves at Cheongpyoung and Chuncheon were 49% and 51 % respectively. The average leaf acidity and bark acidity at Cheongpyoung and Chuncheon were respectively pH 4.8 and pH 4.9 in leaf, pH 5.3 and 5.4 bark. The average water soluble sulfur content in leaves showed a significant difference between Cheongpyoung and Chuncheon of 0.133% and 0.053% respectively.

Keyword: Pinus Koraiensis, leaf acidity, bark acidity, water soluble sulfur contents

적요

본 연구는 환경이 다른 두 지역의 잣나무 잎과 수피를 채취하여 비교 분석, 자동차 배기가스와 수목의 관계 연구를 위한 기초 자료를 제공하는데 그 목적이 있다.
매윌 경춘가도변의 청평과 강원대학교 학술림에서 잣나무 잎과 수피를 채취. 잣나무의 엽중수분함량, 엽중산도, 수피산도, 엽중수용성황함량을 측정하여 다음과 같은 결과를 얻었다.
1. 두 지역의 엽중수분함량을 비교해 보았을 때 학술림 잣나무 잎의 수분 함량이 다소 높게 나타났으나, 그 차이는 현저하지 않았다.
2. 엽중산도와 수피산도에 있어서는 경춘가도 잣나무림의 잎과 수피에서 산도가 다소 높은 것을 알 수 있었는데, 엽중산도는 pH 4.8과 pH 4.9, 수피산도는 pH 5.3 과 pH 5.4 로 현저한 차이는 보이지 않았다.
3. 엽중수용성황함량은 가장 뚜렷한 지역간 차이를 보였으며, 평균적으로 청평(경춘가도변)지역은 0.133% 를 학술림은 0.053% 의 수용성황함량을 나타냈다.
