In carnation, Dianthus caryophyllus L. cv. Hanacy, initiation of flower primordia was followed by mobilization of polysaccharides from leaves to developing flower buds and mature flowers. This process functioned by integrative activities of amylase and invertase, ensuring abundant flow of the mobilized carbohydrates from the source to the sink. Successive stages of floral development exhibited different sink strengths as indicated by amylase and invertase activities and carbohydrate contents in stem apices, which increased with progression of floral development.
