Abstract
Sucrose is the main oligosaccharide present in both the cambial region and young-xylem elements of aspen. Raffinose and 1F-[beta]-fructosylsucrose are also present, the former being mainly associated with the xylem and the latter with the "soft xylem". A protein preparation from the "soft phloem", when incubated with sucrose, produced glucose, fructose and 1F-[beta]-fructosylsucrose. The preparation also exhibited marked [alpha]- and [beta]-glucosidase and [alpha]-galactosidase activities.Keywords
