Sugar content in the sap of birches, hornbeams and maples in southeastern Poland
Abstract: There is very little data on the sugar content of tree sap in Central Europe. In order to fill this gap we measured sugar content in the spring sap of 55 trees from 8 species (six native and two introduced). Sugar content was measured chromatographically using an HPLC Dionex Ultimate 3000 system and CAD detection. The proportion of sugar was highly genus-specific: maples contained sucrose, birches a mix of glucose, fructose and sucrose and hornbeams glucose and fructose. Acer saccharinum had the sweetest sap (4.0%), followed by A. platanoides (3.2%), A. pseudoplatanus (3.2%), A. negundo (2.9%) and A. campestre (2.8%). Birches were slightly less sweet (Betula pendula 2.5% and B. pubescens 2.6%). Carpinus betulus sap contained only 0.9% sugar. The reported values for birches are higher than those reported in other European studies and the values for maples are similar to those for sugar maples in North America. As southeastern Poland has many large populations of maples and birches, a small-scale sugar syrup industry could become an additional source of income for forest owners.
