Potted miniature roses (Rosa hybrida `Belle Sunblaze') held after production in simulated home conditions performed poorly due to premature yellowing and abscission of buds and leaves, and failure of buds to open. These symptoms were accelerated when the plants were exposed to low concentrations (1 ppm) of ethylene. Spray application of 100 ppm 6-benzylaminopurine (BA) reduced yellowing, but had little effect on bud yellowing and flower opening. Application of 1 mM STS prevented the abscission of leaves and buds, although it only partly reduced leaf yellowing. A combined BA and STS treatment greatly improved the postproduction quality of rose plants, particularly if applied 1 day before harvesting.
