โœฆ Synopsis

The presence of tkree water-soluble gibberellins was confirmed in immature seeds of morning-glory (Pharbitis nil). The structure of the main component has been elucidated as 2-O-fl-glucosyl-gibbereUin A s. It shows marked growth-promoting activity on rice seedlings but is far less active on dwarf maize mutants dl, d 2 and d 5.

The occurrence of water-soluble or bound gibberellins has been suggested by several investigators. MVlCAXA~II (1962), OGAWโ€ข (1963, 1966) and ZE~VAAI~T (1966) reported to have found water-soluble gib-

Two new gibberellins, gibberellins Ae6 and Ae~ (GA2~ and GA2:), and their glucosides have been isolated from immature seeds of Japanese morning-glory (Pharbiti8 nil), together with GA s and its glucoside. GA~6, GA2~ and their glucosides showed only slight growth-promoting activities on seedlings of

Two new gibberellins, Canavalia gibberellin-I (CG-I) and Canavalia gibberellin-II (CG-II), were isolated from immature seeds of sword bean, Canavalia gladiata DC. The molecular formulas C19t{2207 and C19H2~O6, were assigned to CG-I and CG-II, respectively, on the basis of high resolution mass, infra
