| Abstract:
Lilium longiflorum 'Nellie White' bulbs forced under an 8-hr duration of fluorescent light at 400 μmol m-2 sec-1 were acceptable for commercial sales. The total number of flowers initiated was not influenced by light intensity or duration during forcing. The number of flowers reaching anthesis was influenced by light duration. Ancymidol was effective in reducing internode elongation. Silver thiosulfate as a spray, at reproductive meristem formation, prevented flower abortions under natural or 50% reduced light. | |
