Abstract

The Kalanchoe daigremontiana CAM plants exhibit very low sensitivity to the action of sulphite dioxide. Fumigation for a week with 3 ppm SO2 leads to an increase in the dismutation rate of the oxygen radical expressed in units of SOD activity and an increase in SOD activity itself. This strong increase disappears 100 h after fumigation. A transient increase in SOD activity represents an adaptation mechanism to oxidative stress caused by SO2.
