Tissue and cell culture of New Zealand Pterocladia and Porphyra species
Seaweeds are not currently cultivated in New Zealand, where bacteriological agar is produced from wild populations of Pterocladia lucida and P. capillacea. The possibility of harvesting and processing New Zealand Gracilaria is being considered, and the potential for mariculture of agar seaweeds is being examined (Christeller et al., 1983; Marsh, 1985). Our research on algal tissue culture has accordingly been directed towards developing protoplast and micropropagation techniques for New Zealand agarophytes. Our current emphasis is on Pterocladia, but we are also working on Porphyra columbina because Porphyra species have proved amenable to tissue and protoplast culture in other studies (e.g., Polne-Fuller amp; Gibor, 1984 and references therein).
