Tóm tắt

AbstractSynthetic compounds that act like phytohormonal ‘superauxins’ have been among the most successful herbicides used in agriculture for more than 60 years. These so‐called auxin herbicides are more stable in planta than the main natural auxin, indole‐3‐acetic acid (IAA), and show systemic mobility and selective action, preferentially against dicot weeds in cereal crops. They belong to different chemical classes, which include phenoxycarboxylic acids, benzoic acids, pyridinecarboxylic acids, aromatic carboxymethyl derivatives and quinolinecarboxylic acids. The recent identification of receptors for auxin perception and the discovery of a new hormone interaction in signalling between auxin, ethylene and the upregulation of abscisic acid biosynthesis account for a large part of the repertoire of auxin‐herbicide‐mediated responses, which include growth inhibition, senescence and tissue decay in sensitive dicots. An additional phenomenon is caused by the quinolinecarboxylic acid quinclorac, which also controls grass weeds. Here, the accumulation of phytotoxic levels of tissue cyanide, derived ultimately from quinclorac‐stimulated ethylene biosynthesis, plays a key role in eliciting the herbicidal symptoms in sensitive grasses.
