Abstract Protoplasts were isolated from tissue fragments (<1 mm2) of three Philippine cultivars of Kappaphycus alvarezii: the giant cultivar, cultivar L and Bohol wild type, by enzymatic dissolution of cell walls. Yields of viable protoplasts from young and old thalli (apical, middle, basal segments) were compared at various temperatures, duration of treatment and pH using eight combinations of commercial enzymes (abalone acetone powder and cellulase), and prepared extracts from fresh viscera of abalone (Haliotis asinina) and a terrestrial garden snail. Isolated protoplasts were grown in various culture media, temperatures, photoperiods and irradiance values to determine the conditions that favor germination and growth. |
