Abstract:

Gametophyte morphology of Sphaeropteris brunoniana under four culture conditions were investigated. Results showed that the gametophytes cultured on humus soil and crimson soil were different in the shape of the prothallus and sexual reproduction. On the other hand, the shape of filament and prothallus of the gametophytes cultured on improved Knop′s agar medium were also quite different under different illuminations .

Key words: Sphaeropteris brunoniana
