E. bicolor var. bicolor was evaluated as a cut flower crop. Flowering-size bulbs weighing more than 66 g were obtained in one year from 9.5-g bulblets. Bulb mass was not influenced by the amount of slow-release fertilizer applied. Postharvest treatment of bulbs at 35 deg C for 7 days increased flowering percentage, particularly when bulbs were grown without reduced watering. When bulbs were grown with reduced watering, the 35 deg treatment was not required for 100% flowering. Bulbs stored at 20 deg C for 2 months flowered in 60-69 days and produced 10 flowers on a stem longer than 47 cm. Plants flowered in 39 days after planting when forced at 27 deg . GA3 at 1000 mg/litre as a bulb-dip did not accelerate flowering. Flower longevity was increased 50% by the presence of sucrose or 8-hydroxyquinoline citrate in the vase solution.
