초록

This study was conducted to analyze the influence of simulated acid rain on leaves of Liliodendron tulipifera seedlings. The seedlings were treated with four levels of simulated acid rain with pH of 5.6,4.9, 3.9 and 2.9, and then chlorophyll contents and the degree of foliar damage were investigated.
Differences were statistically significant among treatments in chlorophyll contents in all of the tested soils. The total contents of chlorophyll tended to decrease as the simulated acid rain treatment was maintained. Chlorophyll contents, however, did not decrease according to the decrement of pH levels.
Foliar damage increased as the simulated acid rain was maintained in all tested soils. Especially, the damage dramatically increased between May and July as the acidity increased. As the treatment of simulated acid rain continued, deformed new leaves appeared. In all treatments except the control,the leaves turned brown and the damage increased with time. Necrotic spots appeared during the first month of treatment at the pH level of 2.9 in all soil types. The damage by acid rain should be considered when we plant Liliodendron tulipifera.
