A new technique for the culture of fern gametophytes.
Fern gametophytes initiated from spores grew successfully when immobilised in reticulate polyurethane foam in liquid shake cultures. Colonisation of this matrix was complete seven days after medium inoculation and appeared to be a completely passive process. Yield (dry weight) was greater than that from liquid grown cultures.
