dc.description.abstractStudies were performed to determine the concentration of soluble carbohydrates and starch in chrysanthemum plants at various stages of vegetative and floral development. Leaves of pot chrysanthemum (Chrysanthemum morifolium 'Charm' or 'Favor') grown under full irradiance had more soluble carbohydrates and starch than those grown with 65% irradiance reduction. Both showed clear diurnal variation in carbohydrate concentrations. Inflorescences exhibited no diurnal fluctuations in total soluble carbohydrate (TSC). Sucrose was the only translocated carbohydrate in chrysanthemums in quantities detectable by HPLC. In a postproduction environment, leaf and stem TSC remained relatively unchanged while inflorescence TSC decreased significantly. Reducing sugars (glucose + fructose) accounted for up to 84% of the inflorescence TSC. Relative levels of starch and fructans over time suggests an alternate use of fructans and starch as pools of available reserve carbohydrate during floral development. Fructans were shown to decrease in polymerization in both petals and inflorescences as petals expanded.
