Reduction of postproduction quality loss in potted miniature roses.

Potted miniature roses (Rosa X hybrida L. 'Belle Sunblaze') held after production in simulated home conditions (21C, continuous fluorescent light) yellowed prematurely, flower buds and leaves abscised, and flower buds failed to open. These symptoms were accelerated when the plants were exposed to low concentrations (1 microliter.liter-1) of ethylene in the absence of inhibitors. Spray application of 100 microliter BA/liter reduced leaf yellowing but had no significant effect on flower opening or bud abscission. Spray application of 1 mM silver thiosulfate (STS) strongly promoted flower display but did not prevent leaf yellowing. A combined BA and STS treatment greatly improved the postproduction quality of rose plants, particularly if applied 1 day before harvest.
