|Abstract:||Zone gas is an alternative in the control of fungi in seeds and is advantageous in discarding the need for storage or disposal of chemical containers. The objective was to test different concentrations and times of exposure to ozone gas, in the control of pathogens in pepper seeds, as well as its effect on physiological, biochemical quality. The experimental design was completely randomized, with four replications, in a 6x2 factorial scheme, involving 6 exposure times (0, 20, 40, 60, 80 and 120 minutes) and 2 ozone concentrations (10 and 15 g m-1 ). In the health test, a chemical treatment (6x2) + 1 (fungicide Captan®- Captana) was added. Subsequently, the seeds were evaluated through germination tests, first germination count, tetrazolium, electrical conductivity, emergence speed index, emergence and health. Biochemical analysis was performed for alcohol dehydrogenase (ADH), malate dehydrogenase (MDH), catalase (CAT) and superoxide dismutase (SOD). The ozone treatment at the tested concentrations and times does not interfere with the physiological and biochemical quality of pepper seeds. Ozone gas at the concentrations studied, after 20 minutes, improves the sanitary quality of the seeds.|
