135. Allelopathic Potential Effects of Russian Knapweed (Acroptilon repens) on Germination and Plumule Growth Characteristics of Wild Barley (Hordeum spontaneum). Mohammad Reza Roosta Nejad1, Forough Abbasi1, Reza Ghorbani2, Mohammad Bazoobandi1; 1Islamic Azad University of Mashhad, Mashad, Khorasan, Iran; 2Ferdowsi University of Mashhad, Mashad, Khorasan, Iran In order to determine the allelopatic effects of Russian knapweed on wild barley, a bioassay study was conducted. The experiment was based on completely randomized design, with 4 replications. The studied factors were Russian knapweed parts (shoot or root), and concentration of plant extracts (0, 15, 25,30,35,40,45,50,75 and 100 percent). Results showed that the allelopatic effects of Russian knapweed on wild barley were very significant. Plumule and radicle length genus length, percentage and germination rate were significantly reduced. This reduction was higher in shoot compared to roots of Russian knapweed
