FIG. 1 in Intraindividual variation in nuclear DNA content in Durvillaea antarctica (Chamisso) Hariot, Macrocystis pyrifera (Linnaeus) C. Agardh and Lessonia spicata (Suhr) Santelices (Phaeophyceae)

FIG. 1. — Cells of Durvillaea antarctica (Chamisso) Hariot stained with DAPI: A, mitotic figure (mf) of dividing cortical cells (cc); B, uninucleate cortical cells; C, D, mature antheridia (ma), antheridia germinative cells (agc), antheridium (a) and four-nucleate antheridium (4-na); E, five-nucleate antheridium (5-na); F, antheridia germinative cells. Scale bars: A-D, 5 μm.图1 — 经4',6-二脒基-2-苯基吲哚（DAPI）染色的南极牛皮叶藻（Durvillaea antarctica (Chamisso) Hariot）细胞：A为正在分裂的皮层细胞（cc）的有丝分裂相（mf）；B为单核皮层细胞；C、D为成熟精子囊（ma）、精子囊生殖细胞（agc）、精子囊（a）及四核精子囊（4-na）；E为五核精子囊（5-na）；F为精子囊生殖细胞。比例尺：A-D，5 μm。
