ABSTRACT
The experiment studied the effect of a modified manner
of bulb chilling on the flowering of narcissus, 'Dick Wilden' and 'Flower Drift'
cultivars belonging to the group of double daffodils, and 'Gigantic Star' from
the group of wild daffodils. Four dates of bulb forcing were applied: early,
mid-early, late and very late. One group of bulbs was chilled 'dry' at the temperature
of +5°C and these were placed loose in boxes, while the other was
chilled 'wet', meaning together with the subsoil. The experiment showed that
bulb chilling together with the subsoil contributed to a few days' earlier anthesis
of all three cultivars, and to an increased yield of flowers of 'Gigantic Star'
and 'Flower Drift' only in the mid-early date of forcing.
Key words: narcissi, forcing, wet chilling, dry chilling.
