摘　　要： 研究采用雌雄营养组织块和营养细胞进行培养,以了解坛紫菜单性营养细胞的生长发育情况。结果表明,坛紫菜雌性营养细胞无论在组织水平还是在细胞水平均以产生红色果胞或果孢子细胞为主,有少量细胞发育成精子囊,并放散精子。雄性营养组织和营养细胞以产生精子为主,但不能再分化成丝状体;产生的少量果孢子细胞能发育成丝状体。因此,在室内培养条件下,坛紫菜单性叶状体都能产生两性细胞,它们的差异只是不同性细胞所占的优势不同,并讨论了单性叶状体的产生。 In order to learn more about the growth and development of unisexual vegetative cells of Porphyra haitanensis, female and male vegetative tissues and cells of P. haitanensis were cultured separately in this study. The results showed that many reddish carpogonia or carpospores, few spermatangia and sperms were found in female vegetative tissue and cells. However, in male vegetative tissue and cells, many sperms were observed and they could not develop into conchocelis. Conchocelis could be found from few carpospores. Therefore, both of the thalli of Porphyra haitanensis with single sex could generate male and female cells. The difference was that the advantage of different sex cells was different. The generation of unisexual thalli was also discussed.
