Abstract: The experiments were caried out in 2013 in the laboratory of Experimental Station of Aleksandras Stulginskis University. Treatmens of invistigations: Factor A – weed species of Brassicaceae family: 1) charlock mustard (Sinapis arvensis L.), 2) field pennycress (Thlaspi arvense L.), 3) treacle mustard (Erysimum cheiranthoides L.), 4) shepherd’s purse (Capsella bursa-pastoris L.). Factor B – concentrations of aqueous extracts :1) distilled water, 2) 1: 6250 (ratio of aqueous extracts weed biomass and water), 3) 1: 1250, 4) 1: 250, 5) 1:50, 6) 1:10. The significant highest content of total phenols was in the leaves of charlock mustard and treacle mustard 1,70 ± 0,15 mg g-1 ir 1,81 ± 0,03 mg g-1 of green mass to compare with another morphological parts of weeds, in the flowers of shepherd’s purse and field pennycress (respectively 1,56 ± 0,02 ir 1,70 ± 0,31 mg g-1). The significant least content of total phenols accumulated in the roots of charlock mustard, shepherd’s purse and field pennycress and in the stems of field pennycress to compare with another morphological parts of this plants. The germination of winter wheat was most inhibited (59,8 %) in the aqueous extracts of field pennycress and germination of spring barley was significantly inhibited (42,8 %) in the aqueous extracts of shepherd’s purse. It has been established that the highest shoots and longest roots of winter wheat and spring barley were in the aqueous extracts of treacle mustard, the shortest shoots – were in the aqueous extracts shepherd’s purse and field pennycress, shortest roots were in the aqueous extracts shepherd’s purse. The growth of winter wheat and spring barley roots from 4,1 % to 77,5 % and from 7,4 % to 96,8 % was significantly inhibited under the effect of 1: 6250 , 1: 1250, 1: 250, 1:50, 1:10 concentrations of aqueous extracts of Brassicaceae family weed species
