EFFECTS OF AMINOOXYACETIC ACID ON POSTHARVEST CHARACTERISTICS OF CARNATION

Authors:   David W. Fujino, M. S. Reid, S. Yang
Abstract:
Aminooxyacetic acid (AOA) was tested at concentrations from 0.2 to 5 mM as a vase solution additive for carnation (Dianthus carvophyllus L.) flowers. Flower longevity increased with increasing concentration of AOA in the vase solution up to 2 mM; 5mM AOA caused flower damage. Pulsing carnations for 10 min in 100 mM AOA was also highly effective in extending vase life. The respiration and ethylene production climacterics typical of control carnations during senescence were suppressed and delayed by the presence of AOA in vase solutions. AOA conferred no protection against exogenous ethylene.
