Abstract
A second order rotatable design was used to obtain polynomial equations describing the effects of combinations of sulfur dioxide (SO2) and ozone (O3) on foliar injury and plant growth. The response surfaces derived from these equations were displayed as contour or isometric (3-dimensional) plots. The contour plots aided in the interpretation of the pollutant interactions and were judged easier to use than the isometric plots. Plants of 'Grand Rapids' lettuce (Lactuca sativa), 'Cherry Belle' radish (Raphanus sativus), and 'Alsweet' pea (Pisum sativum) were grown in a controlled environment chamber and exposed to seven combinations of SO2 and O3. Injury was evaluated based on visible chlorosis and necrosis and growth was evaluated as leaf area and dry weight. (Copyright (c) Plant Physiol 1984.)
