Abstract

The senescence of cut carnations (Dianthus caryophyllus, L. cv. Arthur) can be delayed by compounds inhibiting ethylene biosynthesis or its hormonal mode of action. Aminooxyacetic acid (AOA) and aminoethoxyvinylglycine (AVG) extend the longevity of these flowers up to 4 days showing an inhibition in the ethylene production acting on ACC-synthase. Compounds like α-aminoisobutyric acid (AIB), CoCl2, n-propyl gallate, sodium benzoate, acetylsalicylic acid and 8-hydroxyquinoline inhibit the activity of the ethylene forming enzyme (EFE). However only AIB and 8-hydroxyquinoline delay the camations senescence while n-propyl gallate and sodium benzoate hasten it. CoCl2 has phytotoxic effects and acetylsalicylie acid has virtuaUy no effect on senescence. The more effective treatments to extend cut carnations longevity are those made with silver thiosulfate (STS) which interfere with an ethylene binding receptor, preventing the autocatalytic synthesis of the hormone.
