The effect of coolstorage and silver ions on the subsequent ethylene production and vase life of cut carnations: A dissertation submitted in partial fulfilment of the requirement for the degree of Bachelor of Horticultural Science (Honours) in the University of Canterbury

Abstract

The objective of this study was to determine whether coolstorage and subsequent warming of cut standard carnation (Dianthus caryophyllus L. cv. 'Scania') would result in a surge of ethylene greater than normally associated with senescence. If it did, the effects of this surge on flower vase life were to be observed. Secondly, would the application of silverthiosulphate (STS) via the stem prevent this surge of ethylene and therefore extend the vase life of the flowers. The influence of timing (before or after coolstorage) on the effectiveness of the STS application was also to be determined.
