| Popis: | SummaryPost-harvest longevity of Epidendrum ibaguense cut flowers was maximum when treated for 6 h with 1 g m–3 Ethylbloc® [0.14% 1-methylcyclopropene; 1-MCP] followed, or not, by pulsing with 200 g l–1 sucrose for 12 h. This extended the vase-life from 5.5 d to at least 11 d. Cut inflorescences pulsed with 2.0 mM silver thiosulphate (STS) had reduced abscission of flowers, similar to the effect of 1-MCP. When inflorescences were pulsed with 200 g l–1 sucrose alone for 12 h, no effect was observed on the vase-life of the flowers. Flowers kept in a vase solution containing 20 g l–1 sucrose, 150 mg l–1 citric acid, and 200 mg l–1 8-hydroxyquinoline citrate did not influence the longevity of 1-MCP or STS pre-treated flowers, but the vase solution had a small influence on retarding abscission compared with flowers kept in distilled water. Adding 0.2 mM STS to the vase solution improved vase-life 1.74- and 1.45-fold compared with the longevity of flowers kept in distilled water or in vase solution alone, respe... |
