Abstract
β-Glucosidase activity for coniferin (coniferyl alcohol β-D-glucoside) is not present in spruce (Picea abies L. Karst.) seeds but appears in the young seedlings. Lignification starts at ca. day 9 of germination in the vascular bundles. An antiserum against glucosidase 1 isolated from spruce seedlings (Marcinowski and Grisebach, Eur J. Biochem. 1978) was employed for the localization of the enzyme in cross sections of hypocotyls using immunofluorescent technique. The results indicate that at this stage of development the glucosidase is localized at the inner layer of the secondary cell wall. Glucosidase activity was present in all cells of the investigated hypocotyl tissue.
