Abstract
Cut flowers of carnation cv. Scania were placed in a preservative solution (containing an antiseptic, an acidifying agent and an agent for precipitating calcareous compounds) with or without the addition of glucose at 30 g/l. When glucose was present, the activities of sucrose-synthetase, sucrose-P-synthase and glucose-6P-isomerase in the flowers remained high from bud opening to wilting. In the absence of glucose, enzyme activity decreased as the flower aged. The decrease in activity appeared to be related to very low protein synthesis.
