This research was carried out in order to evaluate allelopatical effect of barley (Hordeum vulgare L. cv. Karon) on seed germination and seedling growth of wild mustard seed in Islamic Azad University, Shoushtar Branch, Iran. The experimental design was aranged in a completely randomized design (CRD) with four replications and treatments were 0, 25, 50 and 75% barley aqueous extracts. Results showed that seed germination, lipid peroxidation, seedling fresh weight and seedling length decreased when barley extract concentration increased but mean germination time decreased. Results indicated highest malondialdehyde concentration obtained from 75% barley straw extract (0.0052 mu mol/g f. w.) and highest peroxidase activity was shown in 25 and 50% barley straw extract. The results of this study revealed that barley extracts inhibited the wild mustard seedling growth and increased lipid peroxidation.
