BULBLET PRODUCTION IN VIVO FROM LEAVES OF LACHENALIA (JACQ.)
Leaves of four commercially produced Lachenalia cultivars were severed and planted in vivo. To determine optimal methods of bulblet production, the quantity and quality of bulblets produced at their bases were compared with size and origin of explant, planting depth, base length and base shape. In all cases productivity increased with explant size. Lateral division of explants increased the number of bulblets produced by a given length of explant, but at the expense of size and weight of bulblets. Productivity of proximal sections generally exceeded that of distal sections. No significant correlation was observed between base length and the variables examined. Although in some cases quantity of production responded to planting depth and base shape, these effects in isolation were of less practical importance than the significant interactions observed between variables. Propagation strategies are suggested for each cultivar.
