Glycolytic enzyme activities. Activities of the enzymes involved glycolysis in tubers of HD1 plants. Enzyme activities were measured in the same tuber's samples as the one used for carbohydrate, catecholamine and metabolite analysis. Data represent the mean ± SE of determination on three individual plants per line. Asterisks (*) indicate values that are significantly different from the wild type plants. PFK – phosphophructokinase; PK – pyruvate kinase.
