| Abstract:
We conducted experiments to optimize vegetative propagation of Hippeastrum, and to evaluate whether the subtropical climate of Taiwan could be used for commercial bulb production. Mother bulbs (size of 30-32 cm) were chipped, notched into 12 segments or twin-scaled into 48 segments for daughter bulb formation. The average number of daughter bulbs in chipping, notching and twin-scaling was 13.3, 19.1 and 38.4, respectively, and the average circumferences was 6.8, 6.4 and 4.1 cm after 5 month’s growth. The chipping method was suitable for cutting mother bulb at propagation and the appropriate technique was to make 12-16 segments, depending on the size of the mother bulb. For bulb production, daughter bulbs (3-8 cm) were planted in the open field. The circumferences of the bulbs were 15.2-38.4 cm after fourteen month’s growth, the bigger the daughter bulb at planting, the larger the bulb obtained. | |
