| Abstract: | A series of 13-hydroxygibberellins, gibberellin A1 (GA1), GA19,GA20, GA44 and GA53, were identified by GC/MS (full scan) fromvegetative shoots of tall (cv. Kentucky Wonder) and dwarf (cv.Masterpiece) Phaseolus vulgaris L. It is suggested that GA1is active per se in the control of shoot elongation of P. vulgarisL., and that dwarfism in Masterpiece is not due to shortageof the active GA, but to its low ability to respond to the bioactiveGA.
