| 摘 要： | 通过模拟实验研究富营养化水体中光照对黑藻生长的影响,探索适合黑藻生长的光照条件。设置3个日平均光照水平,分别为6284lx、3913lx、3196lx,测定各个光照条件下的黑藻生长指标和抗氧化系统酶活性指标。结果表明:黑藻在3种光照条件下均可存活,且对水质具有较好的处理效果。其中6 284lx、3 913lx这2种光照条件下黑藻的生长指标和抗氧化系统酶活性指标均无显著差异,但均与3196lx时的这2项指标差异显著。结果显示,在3196lx时黑藻所受胁迫最大,生长状况最差;且推测光照达到一定强度时有可能抑制黑藻的生长。

| Abstract: | By carrying out a laboratory simulation experiment,the effect of light on the growth and physiology of Hydrilla verticillata in eutrophic water was studied,and a light condition suitable for promoting Hydrilla verticillata was determined.Three light intensity levels,daily mean light intensities of 6 284 lx,3 913 lx,and 3 196 lx,were set,and the growth indexes and antioxidant enzyme activity of Hydrilla verticillata in different light conditions were measured.The results indicated that Hydrilla verticillata ... |
