Postharvest characteristics of Limonium 'Chorus Magenta' inflorescences.

Water uptake and stem weight of harvested inflorescences of Limonium cv. Chorus Magenta declined rapidly when the stems were placed in water or a biocide solution. Florets remained open for only approx equal to 5 days after harvest and new florets did not open. The decline in water uptake and stem weight was greatly reduced by a 24-h wetting-agent pulse treatment with Agral LN or Tween 20 at 0.1 or 1 ml/litre. These treatments extended the period over which flower buds continued to open by approx equal to 5 days. The addition of 50 or 100 g/litre sucrose to the 24-h wetting-agent pulse treatment extended flower bud opening to 16 days. The number of open flowers was greater when the wetting-agent pulse treatment was followed by a 20 g/litre sucrose vase-solution treatment.
