从克里米亚费奥多西亚附近的人工池塘Kosharskij采集了小环藻(Cyclotella meneghiniana),在不同条件(淡水、2‰、4‰、8‰和16‰盐度)下进行分离培养。对从单克隆培养的C. meneghiniana和C. meneghiniana和C. kuetzingiana,它们是同种的。在不同盐度条件下培养的细胞非常相似,在阀面fultoportulae的数量,在模式的卫星孔的地幔fultoportulae,并在条纹的长度只有轻微的差异。从4种单克隆培养物中的3种在8‰或16‰盐度条件下分离的单个起始细胞开始的新培养物,在16‰盐度条件下生长,表现出更大的形态变异性,在边缘纹的模式和数量、瓣面fultoportula的数量和位置以及卫星孔的模式方面存在差异。
Cyclotella meneghiniana was collected from an artificial pond Kosharskij near Feodosia, Crimea, isolated and cultured under different conditions (freshwater, 2‰, 4‰, 8‰, and 16‰ salinity). Detailed light- and electron microscope investigations were made of specimens from monoclonal cultures of C. meneghiniana and comparisons made with type material of both C. meneghiniana and C. kuetzingiana, which are conspecific. Cells cultured under different salinity conditions were very similar, showing only slight differences in the number of valve face fultoportulae, in the pattern of the satellite pores of the mantle fultoportulae, and in the lengths of the striae. New cultures started from single initial cells isolated from 3 of the 4 monoclonal cultures at 8‰or 16‰ salinity conditions, and grown in 16‰ salinity showed greater morphological variability, with differences in the pattern and number of the marginal striae, the number and placement of valve face fultoportulae, and the pattern of the satellite pores of...
