Journal Article

· Am. J. Bot.; (United States)
In general, the rate of nitrogen fixation decreased when the lichen Peltigera canina (L.) Willd. was exposed to sulfur dioxide gas at levels from 0.1 to 500 ppm; at 30 ppm, however, nitrogen fixation was stimulated. The chlorophyll content decreased as the level of sulfur dioxide increased.
