| 摘 要： | 选择我国蓝藻水华的优势藻类铜绿微囊藻,进行人工模拟UV-B辐射连续24h照射实验,测定铜绿微囊藻生物量、生理及超微结构指标,探讨湖泊特别是高原湖泊藻类生长对UV-B辐射增强的胁迫响应.结果表明,当辐射时间达到1h时,铜绿微囊藻便开始陆续死亡,但蛋白质含量增加,且叶绿素a浓度保持稳定;当辐射时间少于4h时,细胞内超氧化物... |

| Abstract: | An experiment that Microcystis aeruginosa was exposed to short-term(0-24h) simulated UV-B radiation was carried out to determine the effect of increased UV-B radiation on the phytoplankton growth in lakes,especially lakes in the mountain and plateau.By measuring the biomass,physiological and ultrastructural indices,the response of M.aeruginosa to UV-B radiation was analyzed.When the UV-B radiation exposure time reached to 1h,the M.aeruginosa began to die,but the protein concentration increased and chlorophy... |
