title: Gibberellins in Embryo-Suspensor of Phaseolus coccineus Seeds at the Heart Stage of Embryo Development.
abstract: Gibberellins (GAs) in suspensors and embryos of Phaseolus coccineus seeds at the heart stage of embryo development were analyzed by combined gas chromatography-mass spectrometry (GC-MS). From the suspensor four C(19)-GAs, GA(1), GA(4), GA(5), GA(6), and one C(20) GA, GA(44), were identified. From the embryo, five C(19)-GAs GA(1), GA(4), GA(5), GA(6), GA(60) and two C(20) GAs, GA(19) and GA(44) were identified. The data, in relation to previous results, suggest a dependence of the embryo on the suspensor during early stages of development.
