Assessment of ozone effects on five varieties of tobacco viafumigation method

نویسنده:

چکیده:

To assess the susceptibility of five varieties of tobacco to ozone, nine rounds of fumigation experiments wereperformed. These tobacco varieties were exposed to a range of ozone concentrations in a single-pass chamberfumigation system for short periods. A dose of 7.5 pphm did not produce visible injury in any tobacco variety.Tobacco cultivars; Bel-B, Weather Fleck and ZZ100 exhibited no visible injury up to 26 pphm. However, dosesin excess of 16 pphm caused visible injury in cultivars Bel-W3 and Dynes. Awareness of the susceptibility levelsof these cultivars to ozone assist biological monitoring process in field experiments. Biomonitoring is considered to be a valuable method for ozone assessment for situations where air pollution monitoring by instruments inremote locations is too expensive.
