Investigations on Cytokinins. III. Cytokinin Activity in Lemna minor tRNA Hydrolysates

Abstract
TRNA was extracted from Lemna minor, grown on a cytokinin free medium. Alkaline hydrolysates of the tRNA were active in three cytokinin bioassays: mobilization test, tissue culture and growth of Lemna cultures. Some observations on the growth of Lemna as a bioassay for cytokinins, are given.
