effects of ozone and sulfur dioxide on cotton growth and quality final rept. 14 sep 83-14 mar 85

in a two year study, two varieties of cotton, acala sj-2 and acala sjc-1, were exposed to so2 and ambient oxidants alone and in combination using open top field chambers. two levels of so2, 0.05 ppm and 0.10 ppm were applied for six hours per day, four days per week. so2 at 0.10 ppm reduced yields of sj-2 cotton in both ambient and filter..
