Redukcija toksigenih gljiva roda Fusarium i njihovih mikotoksina u proizvodnji zdravstveno bezbedne hrane na bazi žita (MPNTR - 31023)

Ključne reči: klijanje; kukuruz; potapanje; seme; temperature
Sažetak
Potapanje semena je metod tretmana semena. Primenjuje se neposredno pre setve, pri čemu se seme vlaži do pokretanja procesa klijanja, nakon čega se suši kako bi se sprečilo izbijanje korenka. Cilj ovog ispitivanja bila je procena efekta različitih metoda potapanja semena na parametre klijanja semena kukuruza pri različitim temperaturama. Tretman je vršen potapanjem semena u vodu i rastvore KNO3 (0,1% i 0,5%) pri temperaturi od 25° C u trajanju od 17h. Parametri klijanja praćeni su pri temperaturama 25°C, 15/25°C i 15°C. Potapanje semena je imalo pozitívne efekte na pojedine parametre klijanja pri niskoj i kombinovanoj temperaturi. Najbolji rezultati uočeni su pri potapanju u 0,5% KNO3. Ovaj tretman je smanjio MGT i T50 a povećao GE pri niskoj i kombinovanoj temperaturi. Potapanje semena nije uticalo na klijavost semena. Ovo istraživanje ukazuje na mogućnost primene potapanja u KNO3 u cilju postizanja bržeg nicanja i boljeg sklopa kukuruza pri nižim temperaturama.
