| 摘 要： | 选择具异型世代交替的福建人工栽培的红毛菜为研究材料,对红毛菜丝状体世代的丝状藻丝及孢子囊枝等阶段进行了较系统的核分裂观察研究,探讨红毛菜核分裂特征.结果显示:红毛菜营养藻丝和孢子囊枝细胞均为二倍体细胞,2n=8,其核分裂显示为有丝分裂的过程；同时,丝状体阶段细胞核分裂至前期末均会出现同源染色体配对现象,显示有丝分裂同源染色体配对行为是红毛菜丝状体核分裂的一个重要特征. |

| Abstract: | Nuclear divisions of Bangia conchocelis including vegetative and sporangial phases were systemically studied in this research.The Bangia sample was collected from the cultivation frames of Fujian Province.The results showed that Bangia conchocelis has a heterogenesis life history.Both the vegetative and sporangial branch cells of Bangia conchocelis were diploid with 2n=8 chromosomes and the nuclear division was mitosis.Homologous chromosome pairing could be observed till the late prophase in cells of both phases,which proved that somatic chromosome pairing was an important characteristic of nuclear division of Bangia conchocelis cells. |
