Impact of Alternaria alternata on seed germination wheat

Abstract

Investigation of the effect Alternaria alternata on seed germination of wheat were tested on three varieties of Victory, Renaissance and NS 40 S. Seed germination is the ISTA rules, in order to elucidate the effect of primary and secondary infection pathogen A.alternata on seed natural and conditioned seeds were placed tests with seeds untreated, treated with NaOCl and fungicide Tycoon included. The high rate of seed germination was found in all three experiments. The correlation coefficient between secondary infection of seedlings with A.alternata and germination of wheat was -0.69 to -0.76, depending on the variety, indicating that the rate of infection has no significant effect on seed germination.

Ispitivanje uticaja gljive Alternaria alternata na klijavost semena pšenice testirano je na tri sorte Pobeda, Renesansa i NS 40 S. Prema ISTA pravilima, a u cilju utvrđivanja uticaja primarne i sekundarne infekcije patogena A.alternata na klijavost naturalnog i dorađenog semenskog materijala, postavljeni su testovi sa semenom bez tretiranja, tretirano sa NaOCl i fungicidom Tycoon-om. Visoka stopa klijavosti semena je utvrđena u sva tri eksperimenta. Koeficijent korelacije između sekundarne zaraze klijanaca sa A.alternata i klijavosti semena pšenice iznosio je -0.69 do -0.76 u zavisnosti od sorte, ukazujući da infekcija nema značajan uticaj na klijavost semena.
