The aim of the investigation was to establish the level of atrazine resistance of Chenopodium album L. and Amaranthus retroflexus L. populations collected from different localities in Serbia. Resistant population of the same weed species from Great Britain was used as a know reference. We measured chlorophyll a fluorescence and relative chlorophyll content using SPAD-Meter, as a nondestructive method in order to compare the resistance in weed species. The results showed that chorophyll fluorescence was most sensitive method for distinguishing triazine resistant and susceptible plants compared with SPAD-Meter. In the populations of Chenopodium album L. and Amaranthus retroflexus L. - collected from Zemun Polje, Surcin and Belgrade atrazine resistance was not confirmed.
