Abstract
Nine experimental designs were run to determine the effect of sulfur dioxide on the important Southeastern oat variety - Carolee. The designs were run under controlled conditions and looked at sulfur dioxide concentration (25-300 pphm), ozone interactions, growth and exposure temperatures, growth and exposure humidities, growth and exposure light intensities, nutrient sulfur levels, number of exposures and exposure ages, and a screen for growth conditions. Plants were grown to from 28 days to 84 days before final harvest. Top dry wt, root dry wt, number of tillers and injury were determined for all experimental designs except no. 5 and no. 8. The fifth design also included yield measurements and the eighth did not include the biomass data. The 75 pphm treatments for 1.5 hrs were close to a threshold dose. Growth environmental factors affected the response of the plants and in some cases exposure conditions caused an effect. Sulfur nutrition was a significant factor and showed an interaction with SO2 concentration on several response measures. Foliar injury was highly correlated with growth reductions.
