Abstract

Endogenous gibberellins (GAs) were extracted from suspensor, embryo and integument of very young seeds of Phaseolus coccineus L. and detected by combined gas chromatography-mass spectrometry (GC-MS). Results show the presence of one C20-GA, GA44 and five C19-GAs in the suspensor: GA1, GA4, GA5, GA6 and GA8, and four C19-GAs in the integument: GA1, GA5, GA6 and GA8. Only traces of GA1 and GA5 were identified in the embryo. A compound structurally related to GAs was identified as tetrahydroxy-Kauranoic acid in suspensor, integument and, only in trace amounts, in the embryo.
