INVESTIGATION of carbohydrate metabolism, carried out with lignified grape-vine1, proved the sugarstarch interconversion to be characteristic for this plant as in other woody plants2. The changes in the vines, both those which spend the winter on the rootstock, and the others cut off and stored in the pit, can be characterized by a sugar→starch conversion in the late summer, by a starch→sugar in autumn, respectively, early in the winter, and at the beginning of spring once more by a sugar→starch conversion3.
