采用不同浓度(0 g/L、10 g/L、30 g/L、40 g/L、50 g/L)的种植水比较了菖蒲(Acorus calamus)、黑藻(Hydrilla verticillata)、苦草(Vallisneria natans)、绿狐尾藻(Myriophyllum verticillatum)和水蕹菜(Ipomoea aquatica)对铜绿微囊藻(Microcystis aeruginosa)的抑制能力,探讨了其中抑制能力最佳的种植水对铜绿微囊藻的生理影响。结果表明:5种种植水均对铜绿微囊藻产生了化感抑制作用,且均随浓度升高抑制作用增强,50 g/L苦草和水蕹菜种植水的平均抑藻率分别为90.30%和86.05%。在40 g/L水蕹菜及苦草种植水分别作用下,铜绿微囊藻细胞超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性于...

The inhibitory effect of aquatic plants (Acorus calamus, Hydrilla verticillata, Vallisneria natans, Myriophyllum verticillatum and Ipomoea aquatica) on Microcystis aeruginosa were assessed, which culturing with different concentration of aquatic plants filtrates (0 g/L, 10 g/L, 30 g/L, 40 g/L and 50 g/L). Results showed that the biomass of M. aeruginsa was suppressed when culturing with the selected 5 aquatic plants filtrates respectively, the inhibitory effects increased with the concentration of filtrates. The average inhibition ratio of Vallisneria natans and Ipomoea aquatica filtrates (50 ...
