Abstract
A decrease of storage temperature to 25, 20 or 17°C after 4 weeks at 30°C accelerated root emergence and thereby advanced planting date of dry Freesia corms.
Storage at 30°C for 4 to 8 weeks, followed by storage at 20°C till root emergence reduced the period of dormancy by about 30%. A treatment with 50 μl.l-1 ethylene for 6 hrs on the last day of storage at 30°C had a small promotive effect on root emergence.
Storage at 30°C for 4 to 8 weeks, followed by storage at 20°C till root emergence reduced the period of dormancy by about 30%. A treatment with 50 μl.l-1 ethylene for 6 hrs on the last day of storage at 30°C had a small promotive effect on root emergence.
Neither the change of temperature during storage, nor a treatment with ethylene affected the time from planting till flowering.
Flower quality was not affected by storage temperature.
Ethylene increased the number of flowering stems, but decreased weight and length of the flowering stems.
