Abstract
Three enzymes involved in sucrose biosynthesis were studied: sucrose-synthetase (EC 2.4.1.13), sucrose-phosphate synthetase (EC 2.4.1.14) and glucose-6-phosphate-isomerase (EC 5.3.1.9). When the floral branch of the Scania carnation was supplied with a glucose solution, the capacity of these 3 enzymes remained high during wilting. In the absence of glucose, the enzymatic activity decreased during flower senescence. This decrease in activity seemed to be related to very low protein synthesis.
