LOCALIZATION OF RESERVE MOBILIZATION DURING SCALET FORMATION ON EASTER LILY SCALES
When Easter lily bulb scales are removed and placed in a moist environment, new bulbs ("scalets") arise at the base of the original scale, thus providing a practical means of clonal propagation. To determine regions of the parent scale responsible for the early dry weight increase of the new scalet, investigations were conducted on the localization of starch hydrolysis and accumulation of soluble sugars in basal, central, and apical regions of the parent scale. Over a six week period, starch concentration decreased initially in the apical region, followed by the central region. Soluble sugars increased in apical areas over this same time period. These changes became more pronounced after 31 weeks. These findings indicate that the apical region of a lily scale is of primary importance in supplying dry matter for the initiation and early development of the new scalet, in contrast to the adjacent, basal region.
