Title	Biologically active secondary metabolites of barley. II. Phytotoxicity of barley allelochemicals
Journal	Journal of Chemical Ecology
Year	1994

Pages	2231-2244

Abstract	The release of alkaloids by barley was quantified by HPLC Hordenine was released from the roots of barley in a hydroponic system for up to 60 days The amount reached a maximum, 2 micrograms/plant/day, at 36 days, then declined Effects on white mustard by hordenine and gramine included reduction of radicle length and apparent reduction in health and vigor of radicle tips Transmission electron microscopic examination of white mustard radicle tips exposed to hordenine and gramine showed damage to cell walls, increase in both size and number of vacuoles, autophagy, and disorganization of organelles The evidence of the morphological and primary effects of barley allelochemicals at the levels released by living plants indicates that the biologically active secondary metabolites of barley may lead to a significant role in self-defense by the crop
