Gk. Burge et al., POSTHARVEST CHARACTERISTICS OF LIMONIUM CHORUS MAGENTA INFLORESCENCES, New Zealand journal of crop and horticultural science, 26(2), 1998, pp. 135-142
Water uptake and stem weight of harvested inflorescences of Limonium '
Chorus Magenta' declined rapidly when the stems were placed in water o
r a biocide solution, and florets remained open for only c. 5 days aft
er harvest. The decline in water uptake and stem weight was greatly re
duced by a 24-h wetting-agent pulse treatment of 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 c. 5 days. The addition of 50 or 100
g/ litre sucrose to the 24-h wetting-agent pulse treatment extended ne
wer bud opening to 16 days. However, the number of open flowers was gr
eater when the wetting-agent pulse treatment was followed by a 20 g/li
tre sucrose vase-solution treatment.
