| Abstract:
This research was conducted to study: leaf cutting propagation of Lachenalia aloides Engl. ‘Pearsonii’ as influenced by leaf cutting preparation, propagation medium and temperature during propagation; inflorescence initiation as influenced by bulb storage temperature; and flowering as influenced by bulb size and storage temperature. Proximal segments of approximately 1/3 of the leaf were the best source for bulblet number and regeneration percentage. Optimal propagation conditions were in temperatures of 20°C, and a peatmoss: perlite (1:1, v/v) planting medium. Bulblets originated from parenchyma cells near the vascular bundle sheath. Flowering size bulbs that weigh>1.5g were produced from bulblets after one growing season. Inflorescence initiation and flowering were accelerated by storing bulbs at 20°C and forcing at 15°C, respectively. | |
