Aqueous extraction of gibberellins from pea.

Aqueous buffers were used to extract gibberellin-like substances from pea tissue. The method possesses several distinct advantages when compared with extraction methods using organic solvents. Aqueous buffer extracts can be prepared more rapidly and produce extracts which are free of pigments and other alcohol soluble materials.Extraction of pea with aqueous buffer has indicated the presence of two gibbrellin-like substances in addition to those previously described.
