✦ Synopsis

Ethylene, applied as ethephon, inhibited the elongation of etiolated, axillary potato shoots cultured in vitro and it stimulated radial growth along the whole length of these shoots . The same phenomena were observed when ACC, the precursor of ethylene, was added to the medium, whereas silver ions reversed these effects . However, tuber formation in vitro was suppressed by ethephon. This indicates a dual role of ethylene in the induction of tuber formation in potatoes : it had a positive effect by blocking the elongation of stolons and it suppressed tuber initiation .
