| Abstract: | "OBJECTIVE: To research the algal inhibiting effects of two species of allium plants chives and leeks to provide theoretical basis and application for biological control of cyanobacterial blooms. METHODS: The inhibitory effects of different concentrations of leeks and chives (chives stem leaf and roots respectively) water extracts on M. aeruginosa were studied. RESULTS: The three kinds of water extracts from leek, chives stem leaf and chives roots respectively all had distinct inhibitory effects on M. aeruginosa, and their inhibitory ratios of lowest concentration group (5%, V/V) were 60.8%, 65.0%, 97.8%, respectively. Compared with the control group, the densities of M. aeruginosa in all experiment groups were lower than the control groups in the same period, and the inhibitory effect were more obvious with the increase of the water extract concentrations. Among them, chives roots water extracts had the best inhibitory effect on M. aeruginosa, to the fifth day, M. aeruginosa almost completely dead of the lowest concentration (5%, V/V) and the EC50 was 2.28 g/L fresh weight. CONCLUSION: Chives roots water extracts have a very good algal inhibiting effect, which can be developed an efficient and ecological security algistat" |
