Gibberellin A19 (GA19) and GA24 were identified by gas chromatography-mass spectrometry from growing shoots of four strains of three species of D ioscorea, D. bulbifera var. vera, D. pentaphylla and D. oppositifolia (yams), which are distributed in the subtropical and tropical regions of Asia. An earlier report indicated the presence of several GAs including GA19 and GA24 in a cultivated temperate species of East Asia, D. opposita; these findings suggest possible coexistence of two GA
