초록
Induction of regeneration and maturation for the free-living gametophytes of Ecklonia cava Kjellman was conducted under various temperature, irradiance and photoperiod conditions. Culture conditions for female or male gametophyte fragments were 4 temperature (5, 10, 15 and 20℃), 4 irradiance (5, 10, 20 and 40μmol･m-2･s-1) and 3 photoperiod (14:10, 12:12 and 10:14h L:D). Female and male gametophyte fragments were maintained in active regeneration without reaching sexual maturity under 5~10℃, 5~10 μ㏖･m-2･s-1, 12:12h or 10:14h (L:D) and 15-20℃, 20-40μmol･m-2･s-1, 14:10h (L:D), respectively. Sexual maturation of female and male gametophytes facilitated under 15℃, 20-40μmol･m-2･s-1, 14:10h (L:D) and 5-10℃, 5-10μmol･m-2･s-1, 10:14h (L:D), respectively. These results provide basic informations to control the regeneration or maturation of the free-living gametophytes for artificial seed production of E. cava.
Abstract
Induction of regeneration and maturation for the free-living gametophytes of Ecklonia cava Kjellman was conducted under various temperature, irradiance and photoperiod conditions. Culture conditions for female or male gametophyte fragments were 4 temperature (5, 10, 15 and 20℃), 4 irradiance (5, 10, 20 and 40μmol･m-2･s-1) and 3 photoperiod (14:10, 12:12 and 10:14h L:D). Female and male gametophyte fragments were maintained in active regeneration without reaching sexual maturity under 5~10℃, 5~10 μ㏖･m-2･s-1, 12:12h or 10:14h (L:D) and 15-20℃, 20-40μmol･m-2･s-1, 14:10h (L:D), respectively. Sexual maturation of female and male gametophytes facilitated under 15℃, 20-40μmol･m-2･s-1, 14:10h (L:D) and 5-10℃, 5-10μmol･m-2･s-1, 10:14h (L:D), respectively. These results provide basic informations to control the regeneration or maturation of the free-living gametophytes for artificial seed production of E. cava.
