摘要：

Prothallia of Lygodium japonicum (Thunb.) Sw. were aseptically cultured under white light in a mineral solution. Solvent fractionation of the resultant culture medium and subsequent preparative thinlayer chromatography yielded a fraction that induced antheridium formation and inhibited archegonium formation. Combined gas chromatography-selected ion monitoring analysis of this fraction confirmed the presence of gibberellin A9 methyl ester (GA9-me) as an antheridiogen and an inhibitor of archegonium formation. Exogenously applied [3H]GA9 was rapidly converted to [3H]GA9-me in the prothallial tissue. Authentic GA9-me was active to 10-10M in antheridium formation and to 10-9M in the inhibition of archegonium formation. © 1979 Springer-Verlag.
