Abstract

During 2014 allelopathic effects of Xanthium strumarium L. and Abutilon theophrasti Med. extracts to germination and initial development of maize (Zea mays L.), and soybean (Glycine max L.) were studied in laboratory conditions. In addition to the Water extracts out of dry mass of the tested weed species, extracts made by use of hexane, ethyl acetate and methanol in different concentrations were also used. The applied concentrations were 10, 20, 30 and 40 g/l of dry matter made out of weed species in the 3-4 leaf stage of development. Inhibiting effect of water extract from dry matter of X. strumarium and methanol extract from which methanol part was evaporated to maize seed epicotyls and hypocotyls length was established. In comparison to the control, the maximum concentration of 40 g / l of the extract made from Water solution of A. theophrasti showed inhibitory effect on soybean seed epicotyls and hypocotyls length. The applied extracts made out of dry matter of the both of the studied weed species X. strumarium and A. theophrasti reduced maize seed germination for 14.8-26.83% and soybean seed germination for 18.5-35.82%, in comparison to the control in which it was 95% and 92%, respectively. After germination in a climate chamber, epicotyls’ and hypocotyls’ length of maize and soybean seeds was measured three, six and ten days following spraying by extracts.
