Some observations on the nucleic acids content in the different buds of etiolated and green Phaseolus plants

Summary In this paper are presented some observations about the nucleic acids content in the different buds of eight days old green and etiolatedPhaseolus plants.Obvious differences of nucleic acids content and typical changes in RNA/DNA ratio in the bud of etiolated and green plants were found. The probable role of the differences in nucleic acids on the histological and morphological differences that take place with etiolation is discussed.
