SUMMARY Branches of Chenopodium album , including leaves and young inflorescences, were put into a solution of 15 N‐L‐proline in order to absorb the latter with the transpiration stream. After 48 hrs of exposure a number of nitrogen fractions were separated. 15 N was found in free and bound amino acids, especially in arginine, alanine, glutamic and aspartic acid as well as in amino‐lipids and chlorophyll fraction. Proline is considered to be an important source of nitrogen.
