Research Abstract

Quinclorac is one of the auxinic herbicides belonging to the quinolinecarboxylic acid family, and the mode of action has been thought to be the same as with 2, 4-D, an auxinic herbicide belonging to the phenoxyacetic acid family. Quinclorac exhibits high selectivity among grass species, and the primary mechanism underlying its selective action has been considered to be the selective induction of ethylene biosynthesis, which ultimately leads to cyanide accumulation in susceptible grasses. In this study, the mode of action of quinclorac and recognition properties of auxin receptors were investigated. Our results strongly suggest that quinclorac has a different action from 2, 4-D in several susceptible grass species ; quinclorac-induced growth reduction may be caused by ROS, but not by cyanide.
