Abstract

KNOWLEDGE of hormone concentration in rice is very meagre. So far as we are aware, systematic attempts have not been made to assay and to ascertain the nature of hormones in rice grains. Avery, Berger and Shalucha1, in their work on auxin yields from various plant materials, mentioned the auxin content of rice endosperm. Since the publication of their results, improved methods of extraction with greater yield of hormone from plant tissue have been suggested. Hatcher2 has assayed the hormone content of several grains and studied the relation of its concentration with vernalization response; but in his list rice grain was not included. The importance of hormone and its relation to vernalization and photoperiodic response has been emphasized by Gregory and Purvis3, and Cholodny and Cailahjan4.
