Projekat:
Razrada integrisanog upravljanja i primene savremenih principa suzbijanja štetnih organizama u zaštiti bilja (MPNTR - 31018)
Razvoj integrisanih sistema upravljanja štetnim organizmima u biljnoj proizvodnji sa ciljem prevazilaženja rezistentnosti i unapređenja kvaliteta i bezbednosti hrane (MPNTR - 46008)

Ključne reči: regulatori rasta; efikasnost; duvan; pšenica; uljana repica
Sažetak
Osamdesetih godina prošlog veka smatralo se da manipulacija rastom biljaka zasnovana na korišćenju sintetičkih regulatora, predstavlja početak nove ere u poljoprivrednoj praksi. Regulatori rasta (RR) su našli primenu u različitim usevima (strna žita, duvan, krompir, banana, kafa, pamuk, uljana repica) i zasadima (voće, vinova loza, citrusi). U cilju ispitivanja uticaja RR na porast biljaka, odnosno bočnih izdanaka postavljeni su ogledi u usevima duvana, ozime pšenice i uljane repice. Malein-hidrazid kalijum i različite koncentracije RR butralin su primenjeni u duvanu, tebukonazol je primenjen u uljanoj repici, a etefon u pšenici. Analizom rezultata konstatovano je da je primena RR uticala na rast bočnih izdanaka listova duvana, kao i na porast biljaka uljane repice i pšenice. Utvrđene su statistički jasne razlike između kontrole i tretmana kod svih ispitivanih količina RR. U usevu duvana efekat RR je bio izraženiji na dužinu bočnih izdanaka viših spratova, a kod biljaka uljane repice bolji efekat je uočen nakon primene jesenjih tretmana.
