Abstract

A study of the influence of temperature (constant 20°C and changeable 20-30°C) and seed treatment (NaOCl, M-metalaxyl and carboxine + thiram and untreated seed as control) on germination energy, germination and health status of seeds was carried out in laboratory conditions on seed pepper variety Slavonka. The results showed a statistically significant effect of temperature, treatment and their interaction on the germination energy of pepper seeds, while seed germination treatments did not show significant differences at all. The highest germination energy was in the carboxine + thiram treatment at changeable temperature (76%). A statistically significant effect of temperature, treatment and interaction was determined on the development of phytopathogenic fungi Alternaria spp, Cladosporium sp. and Penicillium sp. Temperatures did not show any statistically significant difference in the development of Fusarium spp., nor the interaction of temperature and treatment in the development of Aspergillus spp. Based on our results we can conclude that effective treatments can improve seed quality and reduce the amount of pesticides needed to control the disease.
