Exposure to exogenous ethylene (C2H4) caused corolla abscission of New Guinea impatiens (Impatiens × hawkeri 'Sunfire'). Abscission varied with time of ex- posure and C2H4 concentration. Ethylene at ≥ 1 µl·liter -1 and exposure times of 4 or more hours caused 80% to 100% corolla abscission. Simulated shipping of untreated control plants caused ≈ 65% corolla abscission. Plants pretreated with silver thiosulfate (STS) and (aminooxy)acetic acid (AOA) and subsequently exposed to simulated ship- ping were not different from one another, and both treatments reduced corolla ab- scission to ≈ 20% when applied at 1.0 mM. Plants pretreated with STS and exposed to 'exogenous C2H4 showed 0% abscission, whereas plants pretreated with AOA showed no reduction in abscission when compared with control plants.
