Waxy leaved mustard (Brassicaceae) in scientific name (Boreava orientalis Jaub&Spach) has recently been reported as an alien invasive crop weed in Kurdistan Province, Iran. In order to investigate the effect of allopathic substances of waxy leaved mustard on wheat germination, we conducted laboratory experiment in 2019-2020 in the Faculty of Agriculture, Department of Agronomy and plant breeding, in the laboratory in factorial format based on a completely randomized block design with four replications. Experimental factors included concentrations of extracts of 4 plants (inflorescences, stems, leaves and roots) at 5 levels (0% i.e. control, 1%, 2%, 3% and 4%) . The studied traits included the main germination traits which include germination percentage, germination rate and seed vigor index. Data were analyzed using SAS software (v.8) and LSD test (5%) and graphs were drawn using Sigma plot software (v.12). The highest germination percentage was related to the control treatment which was 73.5% and the lowest germination percentage was 7% which was related to the concentration of 4% plant extract from the inflorescence of the plant (α=0.05). The highest value of germination rate is 32.82 which is a control treatment and the lowest value of germination rate is 2.78 which was obtained with a concentration of 4% of inflorescence extract (α=0.05). The highest value of seedling vigor index was 16.68 which is the control treatment and the lowest value for the treatment of 4% inflorescence extract was 0.075(α=0.05). The results showed that with increasing the concentration of plant extracts, germination indices decrease. Allelopathic substances in waxy leaved mustard plant must be more in the inflorescence and leaf part of the plant than in other parts.
