The effect of light quality on the induction of apogamy in prothalli of Pteridium aquilinum.
Pteridium gametophytes cultured on a medium containing 4% sucrose under various qualities of light exhibit different developmental responses. Under far-red illumination (690-730 nm) apogamy is produced without enhanced gametophytic growth, thus allowing a distinct separation of the specific induction of apogamy from a general enhancement of gametophytic growth.
