Additional lighting of lilies (cv. Enchantment) in the winter to prevent flower-bud abscission

Acta Horticulturae (47): 237-240

Additional lighting of lilies (cv. Enchantment) in the winter to prevent flower-bud abscission

In the Netherlands the forcing of Enchantment lilies in the winter is impeded by the occurrence of flower-bud abscission and blasting. Higher temperatures in the glasshouse promote bud abscission, but the light factor is crucial. The flower buds are most likely to undergo abscission when they are about 1.0-3 cm long.

A high amount of flower-bud abscission was induced after exposing the plants to a 7-day dark period at the stage where the largest flower-buds were 3 cm long. Spraying the plants with silver thiosulphate (STS) prevented abscission. In a greenhouse...

For Wedgwood iris the percentage of blasted flowers was considerably higher at air temperatures around 15 degrees or 18 degrees C. The minimum light (fluorescent) requir...

The ethylene evolution from 3 cm-long flower buds of Lilium X 'Enchantment' increased when the plants were placed in darkness. Also shortening the daily light period led to an increase in ethylene evolution from the buds. Dark-enhanced e...

Flower-bud abscission is influenced more strongly than bud blasting by short light p...
