Razvoj integrisanih sistema upravljanja štetnim organizmima u biljnoj proizvodnji sa ciljem prevazilaženja rezistentnosti i unapređenja kvaliteta i bezbednosti hrane (MPNTR - 46008)

Sažetak
Biljke iz familije Brassicaceae konstitutivno akumuliraju značajne količine sekundarnih metabolita, glukozinolata. Sadržaj glukozinolata u kupusima zavisi od fenofaze razvoja, biljnog dela, ekoloških i agrotehničkih faktora. Usled povreda i oštećenja biljnog tkiva pod uticajem enzima mirozinaze dolazi do hidrolitičkog razlaganja glukozinolata, pri čemu se oslobađaju isparljivi izotiocijanati. Ova jedinjenja su odavno poznati po svom fungicidnom, baktericidnom, nematocidnom i alelopatskom svojstvu. Antifungalni potencijal izotiocijanata biljaka iz familije Brassicaceae potvrđen je prema mnogim fitopatogenim gljivama. Glukozinolati i njihovi hidrolitički produkti izotiocijanati predstavljaju prirodna, biodegradiblna i netoksična jedinjenja biljaka sa velikim antifungalnim potencijalom, što ih čini pogodnim alternativnim merama kontrole patogena u organskoj i integralnoj zaštiti bilja.
