Abstract: | Bulbs of ‘Soleil d'Or’, exposed to smoke generated from smouldering wood and fresh leaves for several hours on each of 4 consecutive days during storage, produced flowers earlier and at a higher rate, even when using bulbs which were too small to flower using normal methods. The smoked bulbs showed an earlier start of floral initiation and faster development. A temperature of 25°C was optimal for storage. Application of ethylene also gave similar promotive effects when repeated 4 times at 10 μl 1?1 for 1–5 h per day. Longer exposure to ethylene or smoke was less effective or had no promotive effect. |
