A CULTIVATION METHOD OF A HYBRID BY FREE-LIVING GAMETOPHYTES BETWEEN UNDARIOPSIS PETERSENIANA AND UNDARIA PINNATIFIDA

摘要

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 100-300m. The cut female and male gametophyte are cultivated at a temperature of 5-20C, 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.
