Abstract
The effects of emasculation, exogenous ethylene, ACC and inhibitors of ethylene production and action on coloration of Cymbidium lips were investigated.
Coloration of attached lips was dramatically hastened by emasculation and exogenous ethylene.
Coloration of isolated lips was hastened by exogenous ethylene and ACC whereas AVG, AOA and NBD delayed it considerably.
The data therefore indicate that emasculation-induced coloration of the Cymbidium lip can be ascribed to the action of ethylene produced in the lip.

The nature of the signal linking emasculation and lip coloration is discussed.
