Abstract:
PURPOSE: A undaria peterseniana mass production method by inducing the regeneration and aging of undaria peterseniana free-living gametophytes is provided by securing the optimal condition for the regeneration and aging of the Undaria peterseniana free-living gametophytes. CONSTITUTION: Zoospores are released from an apothecium site of Undaria peterseniana. The released zoospores are cultured, and form gametophytes. Separate the gametophytes formed into female and male gametophytes. Culture the separated female and male gametophytes until the gametophytes reach the respective diameter of 3-10mm. Cut the cultured female and male gametophytes in the respective size of 50-400 micrometers. Culture the excised female and male gametophytes under the cell count of 3-25 cell/ind., the temperature condition of 5-20deg. C , the illumination of 5-40micromolm-2s-1, and the photoperiod of 10:14(Light:Dark)-14:10(L:D). Cross-fertilize the cultivated female and male gametophytes. Culture the gametophytes in a liquid culture medium of PESI(Provasoli`s enriched seawater media). Culture the female and male gametophytes until the gametophytes reach the diameter size of 5-6mm. Excise the female gametophytes in the size of 50-100 micrometers. Excise the male gametophytes in the size of 60-150 micrometers. Culture the female gametophytes under the cell count of 3-8 cell/ind., the temperature condition of 10-20 deg. C, the illumination of 15-30 micromolm-2s-1, and the photoperiod of 10:14(Light:Dark). Culture the male gametophytes under the cell count of 8-12 cell/ind., the temperature condition of 5-20 deg. C, the illumination of 15-25 micromolm-2s-1, and the photoperiod of 14:10(Light:Dark).

PURPOSE: A growing method of undariopsis peterseniana and a gametophyte is provided. CONSTITUTION: The sporophyte of undariopsis peterseniana and undaria pinnatifida releases zoospores. The released zoospores are grown to form a gametophyte. The gametophyte of undariopsis peterseniana and undaria pinnatifida is separated into female and male. Each of female and male gametophyte is grown until the diameter reaches 1-5mm. The grown gametophyte is homogenized and cut into 100-300μm. The cut female and male gametophyte are cultivated at a temperature of 5-20°C, a illumination of 5-40 M, and a photeperiod of 10:14(Light(L):Dark(D)) - 14:10(L:D). The grown undaria pinnatifida is cultivated with undariopsis petereniana. Each of male and female is grown until the diameter reaches 2-3mm.
