Abstract

1. The activity of some important enzymes of carbohydrate metabolism was investigated in several fractions of homogenized tissues of nectaries from Deutzia scabra and Convolvulus sepium in the secretion-phase. Considerable activity was found for the particle-associated hexokinase and the soluble fructokinase, phosphohexoseisomerase, sucrase, UTP-glucose-1-phosphate-uridyltransferase, acid and alkaline phosphatases, and pyrophosphatase. The activity of phosphoglucomutase was smaller, and that of starch-hydrolases and-phosphorylases and of sucrose-synthetase was very weak. 2. The meaning of these results in relation to the metabolism and the secretion of carbohydrates in nectaries is discussed.
