N2  - Evidence for allelopathic activity in barley and the major temperate cereal crops is reviewed. We believe that the secondary metabolites, gramine and hordenine, produced by barley (Hordeum spp.) play a role in defending the producing plant against interference from other organisms. Our recent work has shown inhibitory effects on a fungus (Drechslera teres) and on armyworm (Mythimna convecta) larvae as well as on a number of plant species. This work and that of others showing activity against bacteria, aphids and mammals suggests a possible physiological resistance to these organisms which may be exploitable through plant breeding. A survey of 43 lines of barley including ancestral and modern types indicates that hordenine production by modern cultivars may already have been inadvertently favored by selection for agronomic traits while the ability to produce gramine may have been reduced or lost during this process
