Abstract

The effects of inhibitors of ethylene synthesis and action on the vase life and quality of fresh and cold-stored ‘Gabriella’ roses (Rosa hybrida L. cv. Gabriella) were investigated. Aminooxyacetic acid (AOA) as a 1-hr pulse at 3 or 10 mM had no effect on the longevity of fresh flowers. However, the 10 mM pulse, applied either before or after cold-storage, extended by up to 2.7 days the longevity of roses that had been stored for 3 weeks at 1C. Silver thiosulfate (STS), as a 0.5-hr pulse at 0.5 mM, extended the life of fresh and cold-stored roses by 2 and 3 days, respectively.

Abstract

Treatment of ‘Scania’ standard carnations and ‘Elegance’ spray carnations (Dianthus caryophyllus L.) with silver thiosulate and the biocide Physan before shipment markedly extended shelf life in deionized water after arrival. The treatment extended vase life of ‘Scania’ and ‘Elegance’ 11.5 and 5.2 days, respectively, over controls. Pretreatment of ‘Captain Busch’ gladiolus Gladiolus × hortulanus L. H. Bailey with silver thiosulfate alone or with a 10% sucrose pulse improved the quality of the spikes but did not extend vase life after shipment.
