摘要: Hydroxamic acids are secondary metabolites typical of Poaceae that play a role in cereal resistance against pests and pathogens. The content the hydroxamic acid aglucones DIBOA (2,4-dihydroxy-1,4-benzoxazin-3-one) DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one) was evaluated wild belonging to tribes Triticeae (genera Hordeum Elymus) Aveneae Deschampsia Phalaris). concentration seedling extracts barleys chilense, H. brevisubulatum subsp. violaceum bulbosum negatively correlated with parameters related performance aphids Schizaphis graminum Diuraphis noxia. relevance results obtained for breeding programs aimed at increasing is discussed.
