Abstract:

Carbohydrate reserves were localized in the embryo axis of Quercus alba prior to germination. During the germination process, lipid and protein reserves were translocated from the cotyledons to the embryo axis. Q. alba does not require stratification before germination as does Q. nigra, which was shown earlier to translocate carbohydrates into the embryo axis before germination occurred. The presence of carbohydrates in the embryo axis of Quercus may be a prerequisite for germination in oaks. Forest Sci. 24:486-493.
