Abstract

By combined gas chromatography-mass spectrometry the gibberellin present in suspensors of heart-shaped embryos of Phaseolus coccineus has been identified as Gibberellin A1 (GA1). The amount of GA1 in 2000 suspensors (452 mg), as estimated by gas chromatography, was 4 μg. The presence of GA1 in suspensors of P. coccineus is discussed in relation to our present knowledge of the occurrence of many gibberellins in developing seeds and immature fruits of the same species.
