| 摘 要： | 低温胁迫下,测定了2个不同生境的钝顶螺旋藻(Spirulina platensis)细胞丙二醛含量和电解质外渗量,对钝顶螺旋藻细胞过氧化和质膜透性进行了研究。结果发现,在相同条件下,MDA含量和质膜伤害程度均为S2>S1,S1质膜过氧化程度小于S2,,抗寒性强于S2;随着低胁迫的增强,2个样品的MDA含量均呈升高趋势,细胞电解质外渗增加,细胞过氧化程度加大,质膜透性增强;经低温锻炼后2个样品的MDA量均比直接低温处理的低,质膜的伤害程度也小,说明低温锻炼能增强钝顶螺旋藻对低温逆境的适应性。 |
| 关 键 词： | 钝顶螺旋藻 低温胁迫 低温锻炼 丙二醛 抗寒性 |

| Abstract: | The samples of Spirulina platensis from different habitats were analyzed by the RAPD.The result shows that there are obvious differences in the molecular level between the Spirulina platensis from alkaline lakes in Erdos Plateau and the one from Chad Lake,and the homology of DNA in the amplified polymorphism of the Spirulina platensis only reaches 48.23%.The different habitats and geographical isolation are the primary reasons for the above-mentioned result. |
| Keywords: | Spirulina platensis low temperature stress plasma membrane malondiadehyde cold resistance |
