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: korovi; usevi; sikiminska kiselina; hlorofil
Sažetak
Merenje sadržaja šikiminske kiseline i hlorofila kod hibrida kukuruza, linija soje, populacija C. canadensis and L. rigidum je obavljeno nakon primene 2 kg a.m. ha-1 herbicida TOU­CHDOWN® [aktivna materija: glifosat trimezijum so (sin. sulfosat), 500 g L-1]. Uzorkovanje je urađeno 2, 4 i 6 dana posle primene. Promene sadržaja šikiminske kiseline kod tretiranih biljaka u odnosu na ne tretirane su bile značajne kod svih S biljaka i nisu imale značaja kod R biljaka. Sadržaj hlorofila kod tretiranih biljaka je statistički bio niži u odnosu na sadržaj kod ne teretiranih biljaka kod svih testiranih populacija/linija osim kod hibrida kukuruza (razlike nisu bile statistički značajne).
