The effect of the ether extract of immature bean seeds on the growth of rice seedlings was studied. Attempts were made to separate active principles by paper chromatography.
The growth of the intact coleoptile was promoted by the eluate from the zone of Rf 0.9 in the solvent mixture of isopropyl alcohol/water/ammonia (10:1:1). EIA and IAN showed similar Rf to that of the coleoptile growth-promoting substance of the bean extract. Synthetic EIA was found to be 10 times more effective than IAA on the pormotion of rice coleoptile growth.
On the other hand the growth of the intact foliage leaf was promoted only by the eluate from the zone of Rf 0.65 and inhibited by that of Rf 0.75. Gibberellin A showed similar Rf to that of the leaf growth-promoting substance of the bean extract.
