Abstract
GIBBERELLINS are physiologically defined by their ability to induce shoot elongation in certain dwarf plants and they have been demonstrated in various plant extracts using dwarf maize plants1 and dwarf peas2–4 as assay material. Other assay material includes leaf sections of wheat seedlings2 and sections of cucumber tendrils5. A convenient method employed by Murakami6 involves the use of rice seedlings. Dwarf maize and pea plants, although very sensitive, are less convenient for assaying the several fractions obtained after paper chromatographic separation of plant extracts. An attempt was made to develop a simple means of bio-assay for this purpose.
