| 摘 要： | 对条斑紫菜(Porphyra yezoen sis)离体细胞在含Fe2+培养条件下的生长发育进行了研究。在消毒海水培养基中添 加不同浓度的Fe2+，培养经酶解分离而获得的条斑紫菜单细胞。结果表明，低浓度的 Fe2+能促进其生长发育；而高浓度的Fe2+可以导致苗大量畸变，细胞变小，苗 反复崩解成单孢子。当Fe2+浓度达到50mg/L以上时，细胞完全致死。

| Abstract: | The growth and development of Porphyra yezoensis iso lated cells was studied in the medium with Fe2+. Porphyra yezoensis ce lls separated enzymatically were cultivated in the boiled sea water medium with Fe2+ of different concentrations.The cell survival rate,growth and develo pment were investigated.It was proved that low concentration Fe2+ can acce lerate its growth and development,but high Fe2+may lead to seedlings defor mity, make the cells become small and the seedlings divide into monospores again and again. When the concentration of Fe2+reached over 50mg/L, the cells a ll died. |
