초록

본 연구는 자작나무류의 오존에 대한 잎의 가시적 피해율과 생장 반응을 측정하여 수종별 오존 민감성을 비교하고자 하였다. 시험 재료는 거제수나무, 물박달나무, 자작나무, 사스래나무로 온실에서 양묘하여 포트로 옮겨 심고, 100 ppb의 오존 농도에서 하루 8시간 씩 5주 동안 오존에 노출시킨 후 그들의 가시적 피해율과 잎 수, 잎 면적 및 생장(수고와 직경 상대생장율, 잎, 줄기, 뿌리의 건중량)을 측정하여 수종간, 처리간 차이를 비교하였으며 연구 결과는 다음과 같았다. 4개 수종의 오존에 대한 반응은 매우 다르게 나타나는데 사스래나무를 제외한 3개 수종의 생장은 오존에 의해 크게 영향을 받아 감소하는 것으로 보인다. 특히 초기에 많은 조기낙엽을 나타내는 거제수나무와 가시적 피해율이 가장 높은 물박달나무는 오존에 대해 민감한 수종으로 판단된다. 그러나 사스래나무는 초기에 오존에 대한 영향으로 생장이 감소하지만 오존에 대한 적응을 통하여 생장을 회복하는 내성 수종으로 판단된다.

This study was conducted to compare ozone sensitivity among Betula sp. by measuring visible foliar injuries and growth responses. Four Betula sp.(B. costata, B. davurica, B. platyphylla var.japonica and B. ermani) grown in the greenhouse, were transplanted in the plastic pots. One-year-old seedlings of four Betula sp. exposed to relatively high ozone concentration(100 ppb) for 8 h day$^{-1}$ for 5 weeks in fumigation chamber. We measured visible injuries, leaf numbers and leaf areas at the end of experiments, and growth effects were evaluated by measuring the relative growth rate(RGR) of height and diameter and the dry weights of leaf, stem and root once a week. Four Betula species showed the significant differences for growth responses by the ozone treatment. Growths of three species, except for B. ermani, were significantly reduced by the $O_3$ exposure. B. costata with leaf senescence at the early growing stage and B. davurica indicated highest visible foliar injury rate may be the sensitive species at the 100 ppb ozone concentration. Although the growth rate of B. ermani was reduced by 100 ppb ozone exposure at the early growing stage, B. ermani may be a tolerance species that recover the growth rate with the adaptation for the high ozone concentration.
