Postharvest quality of cut Gypsophila paniculata L. as influenced by environmental conditions during transport.

 

Pulsing cut G. paniculata cv. Bristol Fairy stems with 30% of buds open for 3 h in a preservative that contained 0.2 mM silver thiosulfate and 4% sucrose promoted bud opening and prolonged vase life. Precooling to 1 deg C followed by transportation at 5 deg C, improved the longevity of cut flowers which were hydrated with the preservative, but precooling alone had no effect, especially on those hydrated with deionized water. Subjecting cut flowers to 18-25 deg C or sudden rise in temperature from 1 deg C to 18 deg C increased ethylene and carbon dioxide concentrations within carton boxes during the transport period. This resulted in an increasing number of florets exhibiting petal browning. Maintaining cut gypsophila flowers at 25 deg C for 24 h also caused severe water stress, making rehydration after transport difficult.
