Mycopopulation of maize seeds (2006-2008)

Abstract

A large number of microorganisms' parasite on maize seed. The most important of them are fungi. Blotter method and method of nutrient medium were used to examine the seed health of 90 maize seed samples from eight seed processing centres in the period 2006-2008. The presence of fungi from the genera Fusarium, Penicillium, Aspergillus and Rhizopus was observed on maize seed. According to current regulations, level of infection caused by the fungi observed in all three years was within the normal limits. The percentage of infected samples was 45% in 2006, 40% in 2007, and 32% in 2008. Percentage of infection ranged from 0.25% to 5% in samples where the presence of fungi of the genus Fusarium was detected, while the percentage of infection on maize seed caused by the fungi from saprophite group (Penicillium spp., Aspergillus spp. and Rhizopus spp.) ranged within the limits of 0.25% to 15%.

Seme kukuruza parazitira veliki broj mikroorganizama, među kojima su najznačajnije gljive. Za ispitivanje zdravstvenog stanja 90 uzoraka semena kukuruza u periodu 2006-2008. iz osam doradnih centara, korišćen je metod vlažnog filter papira i metoda izolacije na hranljivoj podlozi. Na semenu kukuruza konstatovano je prisustvo gljiva iz rodova Fusarium, Penicillium, Aspergillus i Rhizopus. Stepen zaraženosti semena kukuruza gljivama u sve tri posmatrane godine bio je u dozvoljenim granicama prema važećim propisima. Procenat zaraženih uzoraka iznosio je 45% u 2006, 40% u 2007. i 32% u 2008. U uzorcima u kojima je konstatovano prisustvo gljiva iz roda Fusarium procenat infekcije je iznosio od 0,25% do 5%, dok se procenat infekcije semena kukuruza gljivama iz grupe saprofita (Penicillium spp., Aspergillus spp. i Rhizopus spp.) kretao u granicama od 0,25% do 15%.
