| 摘要: |
| 研究了不同光照周期对铜绿微囊藻(Microcystis aeruginosa)和绿色微囊藻(Microcystis viridis)生长的影响.按光照周期不同将两种微囊藻各分为五组处理组I[2L/22D]、Ⅱ[5L/19D]、Ⅲ[7L/17D]、Ⅳ[9L/15D]、对照组[12L/12D], 试验期为20d.试验表明铜绿微囊藻实验中处理组Ⅳ[9L/15D]的比增长率和最大细胞数均最大, 超过了对照组[12L/12D].绿色微囊藻实验中对照组[12L/12D]的最大细胞数和比增长率最大.随光照周期的延长两种微囊藻的最大细胞数有增加的趋势.绿色微囊藻对光照周期较铜绿微囊藻敏感.两种微囊藻在每日2h的光照周期下生长均受到抑制. |

| Abstract: |
| This paper dealt with the effect of different light cycle on growth of M. aeruginosa and M. viridis. According to the light cycle, both species was divided into five treatments: [2L/22D], [5L/19D], [7L/17D], [9L/15D] and controlled [12L/12D];and the experiment was lasted 20 days. The results showed that the treatment [9L/15D] of M. aeruginosa had the highest μmax and bmax whiel M. viridis had the highest μmax and bmax in the controlled treatment [12L/12D]. The μmax and bmax of both species increased following the increasing rate of light cycle. |
