목본식물에 대한 Al독성에 관한 기초자료를 얻고자, Al농도별(1.0, 2.5및 5.0mM)수용액과 지하수에 수경삽목한 개나리삽수의 생장관련형질(신초의 생장, 엽수, 엽피해율 및 엽록소함량)을 처리간 비교하였다. 모든 생장관련형질들(신초의 생장, 엽수, 엽피해율 및 엽록소함량)에서 처리간 고도의 통계적 유의차가 인정되었으며. 1.0mM 정도의 Al수용액도 개나리삽수의 생장을 현저히 억제하였다.
To examine aluminum toxicity on woody plants, Forsythia koreana cuttings were grown in the aluminum solution and ground water(pH 6.75). Aluminum solution were prepared 1.0, 2.5 and 5.0mM aluminum potassium sulfate, dilulted with ground water. Shoot growth, leaf number, leaf injury and leaf chlorophyll content were measured and compared among the treatments. In all growth-related characters(shoot growth. leaf number, leaf injury and leaf chlorophyll content), differences among the treatments were highly significant. Forsythia koreana cuttings were severely stressed in aluminum solution more than 1.0mM concentration.
