The main purpose of this study was to select a B. schmidtii population which has high cadmium tolerance and remediation and to determine the difference of cadmium uptake patterns among populations. One-year-old B. schmidtii seedlings were treated with 0, 0.4, 0.8mM CdSO4. 3/8H2O for two months. Cadmium concentrations in different positions of stem and cadmium concentrations and contents of leaves, stems and roots were analyzed. Also soil cadmium concentrations were analyzed. B. schmidtii was highest in root and lowest in shoot tip, showing a gradual decrease from root to shoot tip. The shoot to root Cd concentration ratios were over 1.26. It is concluded that B. schmidtii has good potential for phytoextraction as a shoot accumulator, which can be used for remediation of cadmium-contaminated areas. But tolerance differs between populations. Therefore B. schmidtii should be used as a means of phytoremediation after selection for Cd tolerance is performed.

Cd 처리에 대한 박달나무의 반형매 차대간의 Cd 흡수 및 이동 패턴을 알아보고자 수행한 결과, 잎의 주간 내 위치에 따른 Cd 농도는 지제부에서 높게 나타나고 정단부로 올라 갈수록 농도가 낮아지는 경향을 보였다. 대체로 식물체내에서 Cd의 농도 분포는 뿌리>줄기>잎의 순으로 나타났지만, 가계별, 처리별로 상이한 결과가 나타나 가계간 유전적인 요인이 크게 작용한 것으로 판단된다. 모든 가계의 처리구에서 지상부와 지하부의 Cd 농도 비율이 1.26 으로 나타나 박달나무는 Cd을 흡수하여 지상부로 보내는 축적종의 경향을 갖고 있는 것으로 판단된다. 또한 토양 중금속 농도와 식물체내 중금속 농도의 비도 가계간 차이는 있지만, Cd을 능동적으로 흡수하여 지상부로 이동시키는 Cd 정화 수종으로 판단된다. 하지만 박달나무는 Cd에 대한 반응이 가계간 다양하므로 토양 중 Cd 정화를 위해 이용할 경우, 정화 능력이 우수한 수종을 선발하는 것 뿐만 아니라, 같은 수종 내에서도 내성 능력과 정화능력이 차이가 있으므로 가계 선발이 필요할 것이다.
