Height growth of silver maple, white ash, yellow-poplar, sycamore, eastern cottonwood, and white spruce seedlings was not significantly influenced by 0.15 ppM SO2 for 8 hours/day, 5 days/week. A fumigation treatment of 0.25 ppM SO2 for 8 hours/day, 5 days/week didn't significantly affect height growth of black alder, yellow-poplar, or white spruce seedlings but significantly reduced the height growth of eastern cottonwood, green ash, and sycamore seedlings. Exposure to toxic concentrations of SO2 (1 to 4 ppM) for 2 to 8 hours significantly affected the height growth and caused leaf injury in silver maple and yellow-poplar seedlings.
