title: Isolation of two new gibberellins from immature seeds of Canavalia.
abstract: Two new gibberellins, Canavalia gibberellin-I (CG-I) and Canavalia gebberellin-II (CG-II), were isolated from immature seeds of sword bean, Canavalia gladiata DC. The molecular formulas C19H22O7 and C19H22O6, were assigned to CG-I and CG-II, respectively, on the basis of high resolution mass, infrared and NMR spectra. The growth-promoting effects of CG-I and CG-II on dwarf maize mutants d 1 and d 5, rice seedlings and dwarf peas, Progress No. 5, are reported.
