The role of auxin in the recovery of plant tissue from oxidant treatment was investigated. Treatment of oat coleoptile sections with concentrations of indoleacetic acid (IAA) or 2,4-dichlorophenoxyacetic acid (2,4-D) optimal for normal growth, following pretreatment with moderately inhibiting levels of peroxyacetyl nitrate (PAN) immediately accelerated recovery of growth rate. In some cases inhibition was also less at supraoptimal values of auxin. Treatment of ozone-pretreated tissue with IAA or 2,4-D enhanced inhibition at high levels of auxin and produced an optimal growth concentration level which was lower than for sections not given ozone pretreatment. Auxin treatment also reduced the degree of inhibition in fluoride and iodoacetamide-pretreated sections. Mechanisms by which auxin-induced recovery from inhibition may occur are discussed.
