Abstract	The effects of the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC) and two inhibitors, silver thiosulfate (STS) and aminoethoxyvinylglycine (AVG), were tested in yellow passionfruit (Passiflora edulis f. flaricarpa Degener) acillary cultured in vitro. The organogenic responses were assessed by the number of buds per explant, mean leaf area per explant, and shoot length. ACC-supplemented medium significantly inhibited all evaluated responses at both concentrations tested. When ethylene action and biosynthesis were inhibited, a significant increase in the number of developed buds and average leaf area was observed. Accumulated ethylene and its accumulation rate were significantly greater at 10 μM ACC, with a maximum production rate deteeted: at the 14th day and a decline at the 21st day. The results suggest beneficial effects of ethylene inhibitors on in vitro development of axillary buds and their reliability for use as an alternative approach to evaluate sensitivity of Passiflora species to ethylene. Even though shoot elongation did not differ from that of the control, the inhibition of the ethylene action and its biosynthesis by AVG and STS, respectively, significantly enhanced the number of buds per explant and leaf area.
