Changes of Starch Content in the Storage Tissues of Deciduous Trees During Winter and Spring

Abstract

Starch transformation in relation to spring sap production has been investigated in six North European deciduous tree species from fall till the beginning of bud break in spring. The species examined were: Acer pseudoplatanus L., Betula pendula Roth, Alnus glutinosa Gärtn., Fagus sylvatica L., Quercus robur L., and Fraxinus excelsior L.
