RESUMO

Analysis of extracts from 6300 (1.2 grams fresh weight) Phaseolus coccineus suspensors by combined gas chromatography-mass spectrometry has demonstrated the presence of five C19-gibberellins, GA1, GA4, GA5, GA6, GA8, and one C20-GA, GA44. The major GAs present were GA1 and GA8. Data are discussed in relation to previous results obtained in P. coccineus seed as well as in the embryo-suspensor system.
