S ummary Excised beech mycorrhizas incorporate 14 C into their tissues from dilute bicarbonate solution. The rate is doubled if the mycorrhizas are shaken in ammonium phosphate rather than potassium phosphate. The main distribution is into malic, glutamic and aspartic acids in the presence of potassium. In the presence of ammonium ions glutamine becomes the most strongly labelled compound.
