Distribution of radioactivities in sugars from acetate-2-14C incubation and elemental content of some vascular plants in two diverse habitats of Glacier Bay, Alaska
Essentially six sugars became labeled following acetate-2-14C metabolism in plants distributed in two different communities—pioneer and forest. Of these the bulk of radioactivity resided in glucose, fructose and sucrose. Except for willows, labeled glucose and labeled fructose dominated the plants o...

Essentially six sugars became labeled following acetate-2-14C metabolism in plants distributed in two different communities—pioneer and forest.

For willows, the radioactivities were present in both monosaccharides and disaccharides. This sugar labeling pattern occurred in the alder which for the two habitats tested, was consistent with the general observation. The relative level of the content of magnesium and phosphorus for various plants in the pioneer habitat were no different from those in the forest habitat.
