LONG-TERM COOL STORAGE OF BUD-CUT CARNATIONS

Tight carnation (Dianthus caryophyllus L.) buds of four cultivars were preconditioned in a solution containing silver thiosulphate 550 mg/1 and sucrose (100 g/1) and then stored for 16 to 24 weeks in dry storage at 0 to 1°C. For 24-week storage of the "White Sim", "Keefer’s Cheri Sim" and "Scania 3C" cultivars and for 16-week storage of "Yellow Dusty" (the longest practical storage time for this cultivar) buds were dipped prior to storage in a 0.1% aqueous suspension of Rovral or Sumilex to control fungal rots.

In storage the buds were sealed in polyethylene bags (0.07 mm thickness). During storage, bud fresh weight fell by 8%; changes in O₂ and CO₂ concentrations in the bags during storage are reported.
The buds were opened after storage in a solution containing 200 mg/l 8-hydroxyquinoline citrate, 25 mg/l AgNO₃ and 70 g/l sucrose.
After 20 and 24 weeks storage the flowers had a vase life of about 12 and 6 days, respectively.
