摘　　要：鱼腥藻 5 95 (Anabaenasp 5 95 )、织线藻 2 4 6 (Plectonemaboryanum 2 4 6 )和伪枝藻2 4 8(Scynetonemahofmanni 2 4 8)在两种重金属汞、镉和两种微量元素铜、锌诱导下 ,藻丝细胞均能发生膨大、液泡化现象。不同重金属及微量元素对 3种蓝藻液泡化诱导作用强弱程度不同。汞的诱导作用明显强于镉、铜和锌 ,0 1μmol/L汞可诱导 3种蓝藻发生液泡化。采用压片法均观察到诱导形成的液泡 ,液泡在相差显微镜下显示为圆球形 。Grown in the presence of 2 heavy metals mercury and cadmium and 2 trace elements:copper and zinc, the filamental cells of Anabaena sp 595, Plectonema boryanum 246 and Scytonema hofmammi 248 inflated and vacuolized There were various inducing effects on the three cyanobacteria by different heavy metals and trace elements Mercury gave rise to obvious more intensive effect then cadmium copper and zinc: 0 1μmol/L mercury could induce vacuoles in the cyanobacteria The vacuole could be observed by pressing the sample and it was spherical and transparent in the scope of the phase microscope
