Conclusions
1. The resin is a convenient source of the isolation of the individual gibberellins and other acidic and neutral metabolites.
2. By means of partition chromatography in a column of KSK silica gel treated with phosphate buffer having pH 6.4, it has been possible to separate gibberellins A4 and A7 and an isomer of gibberellin A7-the hydroxylactone acid (II).
3. Gibberellin A13 has been isolated from the resin remaining after the evaporation of the mother solutions from the crystallization of industrial gibberellin, and the structure of the isomeric trimethyl esters obtained from it has been elucidated.
4. For the PG-7 strain, the connection observed previously for the F-6 strain between the relative stimulation of the biosynthesis of the gibberellins and kaurene on the one hand, and the relative suppression of the biosynthesis of highly oxidized diterpenes (kaurenolides and fujenal) on the other hand, has been confirmed qualitatively.
