Tolerance of SO/sub 2/ with respect to sexual reproduction is reported for populations of Lepidium virginicum from the Copper Basin of Tennessee, a region subjected to SO/sub 2/ pollution for the past 75 yr. The offspring of plants from inside and outside the Copper Basin were fumigated with 2130 ..mu..g/m/sup 2/ SO/sub 2/ for 9 h at high relative humidity in replicated experiments. As a result of SO/sub 2/ stress, plants from outside the Copper Basin were less fertile than plants from inside the Copper Basin.
