| Abstract:
The effect of bulb storage and forcing temperatures on growth, inflorescence initiation, and flowering were investigated to produce quality pot plants of Lachenalia aloides, 'Pearsonii' and 'Ronina'. Quality was judged by compactness-short floral stem and leaves at flowering - and early flowering. Bulbs stored at 15°C remained vegetative for 195 days but at 25°C became reproductive in 110 days. Bulbs transferred from 15°C after storage for 195 days to 25°C became reproductive in 85 – 115 days. Bulb storage at 10°, 12.5°, and 15°C for 45 days promoted flowering and reduced leaf length as compared bulbs stored at 20° or 25°C, and when forced at 17°/15°C, day/night. However, the number of florets was reduced by storing bulbs at 10°, 12.5°C, and 15°C. Quality potted Lachenalia plants were produced by storing bulbs after floral initiation at 10° – 15°C for 45 days and force at 15°C. | |
