EFFECT OF CUTTING METHOD ON BULB PRODUCTION OF HIPPEASTRUM HYBRIDUM IN TAIWAN

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.
