Vegetative propagation of Porphyra perforata
Porphyra cultivation is a major aquacultural enterprise in the Orient. The common practice for cultivation of this crop plant necessitates the propagation of two phases of the life cycle of the plants. The conchocelis phase of Porphyra is grown on shells maintained in running seawater under subdued light in special warehouses. In the fall the conchocelis releases conchospores. These spores are made to attach to nets which are subsequently suspended in the sea. The familiar ‘nori’ crop is the second phase of growth. It develops from the conchospores and is harvested from the suspended nets.
