Abstract
Snapdragons (Antirrhinum majus L.) preconditioned or held in floral preservative solutions containing the ethoxy analog of rhizobitoxine showed reduced ethylene production, reduced flower abscission, and increased vase life. The methoxy analog of rhizobitoxine also inhibited ethylene production and increased vase life of snapdragons, but to a lesser extent. Sodium benzoate at 0.2 mm suppressed ethylene production but did not increase vase life; at 2.0 mm sodium benzoate was toxic to flowers.Keywords
