✦ Synopsis

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 nag), as estimated by gas chromatography, was 4 gg. The presence of GA~ 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.
