Sucrose extends the post-harvest life of Sandersonia flowers.

Treating cut S. aurantiaca flowers with propylene (0.5% for 24 h) did not alter the patterns of colour change, fresh weight or respiration which normally occur as the flowers senesce. Silver thiosulfate (STS, 1 mM) did not extend vase life, and postharvest ethylene production by the flowers was negligible, regardless of whether they had been exposed to propylene and/or STS. Vase solutions of 2% sucrose alone or in combination with 200 mg 8-hydroxyquinoline sulfate (8-HQS)/litre extended the vase life of detached flowers. Sucrose also extended the vase life of whole stems. However, exposing whole stems to 8-HQS or higher sucrose concentrations (5, 10 or 20%) caused severe leaf damage, and it appeared that the leaves on the flower stems were more susceptible to postharvest damage than the flowers.
