Abstract
Pleione formosana Hayata, known as the one-foliate orchid, is a native terrestrial orchid in Taiwan.
This study investigated the effect of mother bulb size on flowering and daughter bulb formation, and the application of gibberellic acid (GA) on the bulb growth in Nan-Chung village.
The results showed that the bulb size was in proportion to the flowering percentage, floret number, diameter, scape number and length.
However, the shelf life was not influenced by bulb size.
The number and weight of daughter bulbs after harvest was in proportion to the size of mother bulbs.
Different concentrations of GA3 (0, 25, 50, 75, 125 mg/L) was applied to bulbs by spraying during growth or immersion before planting, and the daughter bulb characteristics were investigated after harvest.
The results indicated that GA3 spraying during growth significantly increased the total fresh weight, diameter and height of daughter bulbs.
