| Abstract:
Eucrosia bicolor var. bicolor Ker-Gawler (Amaryllidaceae) was evaluated as a cut flower. 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. Post harvest treatment of bulbs at 35°C for 7 days increased flowering percentage, particularly when bulbs were grown without reduced watering. When bulbs were grown with reduced watering, the 35°C treatment was not required for 100% flowering. Bulbs stored at 20°C for 2 months flowered in 60 to 69 days and produced 10 flowers on a stem longer than 47 cm. Plants flowered in 39 days after planting when forced at 27°C. Gibberellin (GA3) at 1,000 mg/liter as a bulb-dip did not accelerate flowering. Flower longevity was increased 50% by sucrose or 8-hydroxyquinoline citrate. | |
