초록
The Induction of regeneration and maturation in the free-living gametophytes of Ecklonia stolonifera Okamura was studied at four temperatures (5, 10, 15, and 20℃), four levels of irradiance (5, 10, 20, and 40 μmol m-2 s-1) and three photoperiods (14:10, 12:12, and 10:14 h L:D). Female gametophyte fragments were maintained in active regeneration without reaching sexual maturity under 5~10℃, 10 μmol m-2 s-1, 10:14 h (L:D), whereas the conditions for male gametophytes were slightly different at 20℃, 40 μmol m-2 s-1, 10:14 h (L:D). The sexual maturation of female and male gametophytes was facilitated at 15℃, 20 μmol m-2 s-1, 14:10 h (L:D). These results provide basic information for controlling the regeneration and maturation of the free-living gametophytes for artificial seed production of E. stolonifera.
Abstract
The Induction of regeneration and maturation in the free-living gametophytes of Ecklonia stolonifera Okamura was studied at four temperatures (5, 10, 15, and 20℃), four levels of irradiance (5, 10, 20, and 40 μmol m-2 s-1) and three photoperiods (14:10, 12:12, and 10:14 h L:D). Female gametophyte fragments were maintained in active regeneration without reaching sexual maturity under 5~10℃, 10 μmol m-2 s-1, 10:14 h (L:D), whereas the conditions for male gametophytes were slightly different at 20℃, 40 μmol m-2 s-1, 10:14 h (L:D). The sexual maturation of female and male gametophytes was facilitated at 15℃, 20 μmol m-2 s-1, 14:10 h (L:D). These results provide basic information for controlling the regeneration and maturation of the free-living gametophytes for artificial seed production of E. stolonifera.
