Effects of the cut flower preservative Flower Care varied significantly during the different simulated stages of the production–marketing–consumer cycle. The vase-life of the cut rose Rosa hybrida L. cv. Forever Yours was extended the longest when the preservative was used during the consumer period. When used during the simulated wholesale and retail marketing periods this extension in vase-life was less. The effects of the preservative were least when it was used during the immediate postharvest period. The final size of the flower increased significantly when the preservative was used during the simulated wholesale and consumer periods. The experimental data were used in a regression equation for calculation of vaselife at any concentration of preservative used under the given environmental conditions.

AbstractCut rose stems were pretreated for 24 h with various compounds before being stored in Chrysal solution. Two experiments were conducted to study the effects of different concentrations of aluminum sulphate, ethanol and sucrose in preservative solutions and their combination on flower longevity and post-harvest physiological properties of rose (Rosa hybrida L.) cut flowers cultivars ‘Red Sky’ and ‘Blizzard’. The first experiment aimed to determine the optimum concentration of aluminum sulphate used as a biocide (0, 0.5, 1, 1.5 g·dm−3), ethanol used as a biocide and anti-ethylene factor (0, 4, 8, 12%) and sucrose used as a source of energy (0, 10, 20, 30 g·dm−3). In the second experiment, the most effective concentrations were cumulated in combinations of pretreatment solutions. Single use of chemicals: 0.5 g·dm−3 aluminum sulphate, 4% ethanol and 20 g·dm−3 sucrose extended the longevity of both cultivars by 17, 18 and 19%, respectively as compared to deionized water. In the second experiment, the preservative solution containing all three chemicals at optimal concentrations extended cut flower longevity by 30% compared to deionized water. ‘Blizzard’ has lost its commercial value by 6.6% of the time earlier than ‘Red Sky’. Generally, using a biocide, anti-ethylene and source of energy in a pretreatment solution can maintain the high quality of the cut rose flowers and their vase life.

Abstract Separate experiments showed that current cut rose (Rosa × hybrida) cultivars vary considerably in Botrytis (Botrytis cinerea) susceptibility and ethylene (ET) sensitivity. There was no pattern when considering these two traits together for the 26 cultivars used, and neither trait appeared predictive of the other. Four cultivars were identified that included one each that is Botrytis susceptible/ET sensitive, Botrytis non-susceptible/ET sensitive, Botrytis susceptible/ET insensitive, and Botrytis non-susceptible/ET insensitive. Exposing these cultivars to ET often resulted in reduced vase life and more pronounced negative Botrytis responses (flower Botrytis damage, leaf Botrytis incidence, and frequency of termination due to Botrytis). This was true for ET sensitive and insensitive cultivars, Botrytis susceptible and non-susceptible cultivars, Botrytis inoculated and non-inoculated stems, and stems exposed to ET either before or after Botrytis inoculation and incubation. Thus, even if ET is not thought to have a major influence on a given cut rose cultivar in terms of classic negative ET responses (leaf drop, petal wilt, altered opening rate), ET exposure could have a significant negative impact on that cultivar by exacerbating Botrytis damage. Shipping temperatures and methods can have a strong influence on Botrytis damage, with pre-cooling of shipping boxes before cold storage/transport being beneficial. Index words: Botrytis blight, Botrytis cinerea, cut flowers, floriculture, gray mold, Rosa L. hybrids. Species used in this study: Rose (Rosa × hybrida) focal cultivars ‘Cuenca', ‘Daphnee', ‘Freedom', ‘Vendela'; Botrytis (Botrytis cinerea Pers. ex. Fr.). Chemicals used in this study: 1-methylcyclopropene (EthylBloc); ethylene; silver thiosulfate.

The effects of silver-containing compounds used for prolonging the vase life of cut rose (Rosa hybrida L. `Asami Red') flowers were investigated. Silver nitrate and RNA-Ag+tris (a ribonucleic acid-silver complex and trishydroxymethylaminomethane) increased the vase life by 2.7 days and prevented bent neck of cut rose flowers compared with the control, whereas silver thiosulfate (STS) did not have a significant effect on longevity. Fresh weights of the rose stems pretreated with silver nitrate or RNA-Ag+tris were maintained along with longer vase life. There were higher amounts of Ag+ in the basal parts of the stem in these treatments compared with STS treatment. Bacterial count at the cut surface of stems treated with either silver nitrate or RNA-Ag+tris were lower than STS-treated or control stems. These results indicated that the primary effect of silver-containing compounds on `Asami Red' roses was antimicrobial.
