Abstract
Abstract The structure of a new gibberellin-like antheridiogen from gametophytes of the fern Lygodium circinnatum has been confirmed as the methyl ester of 9,11-didehydro-GA20 by synthesis of an authentic sample from gibberellic acid (GA3). Comparative bioassays of the synthetic compound as an antheridium inducing substance in Lygodium japonicum have demonstrated that it is highly potent, showing activity down to 10−14 M concentrations, and that the high level of activity is correlated with the incorporation of the 9,11-alkene bond.
