The effect of different concentrations of Indole acetic acid (IAA) on spore germination and gametophyte development of Ceratopteris thalictroides, a leptosporangiate fern of the family Pteridaceae found at the marshy places near Sitamata sanctuary in Rajasthan, was observed. The highest spore germination percentage was recorded in the 2 to 6 ppm concentration range of IAA, with minimum in the 10 ppm concentration. The number of cells in the protonemal filament and percentages of 2-D growth, spatulate and cordate gametophyte were highest in the 1 ppm concentration of IAA, followed by the control. Maximum percentages of archegonia and antheridia development were also recorded in 1 ppm IAA and control treatments, with percentages gradually declining from 2 to 10 ppm treatments. However, the maximum percentage of sporophyte development was recorded in 4 and 6 ppm IAA treatments.


Key words: IAA, ppm, 2-D growth, leptosporangiate ferns, sporophytes.
