INFLUENCE OF SEED TREATMENT ON THE HEALTH OF SEED AND INITIAL GROWTH OF PEPPERS

Istraživanje utjecaja temperature (konstantna 20°C i izmjenljiva 20-30°C) i tretmana sjemena (NaOCl, M-metalaksil, karboksin+tiram i netretirano sjeme kao kontrola) na energiju klijanja, klijavost i zdravstveno stanje sjemena provedeno je u laboratorijskim uvjetima na sjemenu paprike sorte Slavonka. Rezultati su pokazali statistički značajan učinak temperature, tretmana i njihove interakcije na energiju klijanja sjemena paprike, dok kod klijavosti sjemena tretmani nisu pokazali signifikantne razlike. Najveća energija klijanja bila je u karboksin+tiram tretmanu kod izmjenljive temperature (76%). Statistički značajan učinak temperature, tretmana i njihove interakcije utvrđen je za razvoj fitopatogenih gljiva Alternaria spp, Cladosporium sp. i Penicillium sp. Za razvoj Fusarium spp. temperature nisu pokazale statistički značajnu razliku, kao niti interakcija temperature i tretmana za razvoj Aspergillus spp. Na temelju naših rezultata možemo zaključiti da se učinkovitim tretmanima može poboljšati kvaliteta sjemena i smanjiti količina fungicida potrebnih za suzbijanje bolesti sjemena.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
