Abstract
Ozone, between 2 ppm for 0.5 h and 6 ppm for 2.5 h did not alter photosynthetic 14CO2-fixation and release of radioactivity in C. rangiformis. A ribitol-induced depression of 14CO2-fixation was overcome by ozone but ribitol-induced release of radioactivity was unaffected. A possible basis for the apparent insensitivity of lichens is discussed.Keywords
