In India, in comparison to angiosperms, few attempts have been made on in vitro studies in ferns and fern-allies. Vascular cryptogams, especially ferns, have not been very favourable material for tissue culture because their vascular system is made up of highly differentiated tissues that are difficult to proliferate into cell masses capable of growth in vitro [10].
