Reduction in petiolar auxin transport has been proposed as one of the functional actions of endogenous or exogenous ethylene as it regulates intact leaf abscission. If this hypothesis is correct, auxin-transport inhibitors should hasten the rate or amount of abscission achieved with a given level of ethylene. Evidence presented here indicates that the hypothesis is correct. Three auxin transport inhibitors promoted ethylene-induced intact leaf abscission when applied to specific petioles or the… CONTINUE READING
