Paper chromatography represents one of the most important technique in the investigation of nitrogen compounds. This study was made to know amino acids contained in the soluble nitrogen fractions and in hydrolyzates of Rice plant by means of paper chromatography, and also to see to what extent these amino-acids are influenced by varying experimental condition and by growing stages. Examination of the plant materials listed in the Tables revealed no marked difference in the amino acids. Two points of interest emerging from this survey may be summarized as follows : In the first place these preliminary observations indicated that among the free amino acids the ubiquity of aspartic acid, glutamic acid, serine, alamine and glutamine is always striking. It would seem that these amino acids and amide occupy a central position in the nitrogen metabolism of Rice plant. In the second place proline is recognized as free amino acid in the pollen only and not in all other samples of this experiment, and supposed to play some special role in the metabolism.
