Localization of Reserve Remobilization During Scalet Formation on Lilium longiflorum Scales

Abstract

When Lilium longiflorum bulb scales we removed and placed in a moist environment, new bulbs ("scalets") arise from the base of the original scale, providing a practical means of clonal propagation. To determine which region of the scale is responsible for the early development of the new scalet, investigations were conducted on the localization of stanch hydrolysis and accumulation of soluble sugars in basal distal and central regions. Over a six week period starch concentration decreases initially in the distal regions, followed by the central region. Soluble sugars increased in distal areas over this same time period These findings indicate the distal regions of a lily scale are important in the early development of the new scalet, in contrast to the adjacen4 basal region.
