| Abstract | Cyanobacterial mass development and their toxins have become an environmental issue recently. In this study,we tested the effects of two crude extracts contained microcystins (MC), including an isolated Microcystisaeruginosa and a water blooms sample collected from Dau Tieng Reservoir, Vietnam, on the seed germination,root and shoot prolongation and wet weight (WW) during the seedling of lettuce and carrot. The MCconcentrations were environmentally relevant, 1-100 ?g/L and the experimental period lasted for 7 days. Wefound that both lettuce and carrot seeds were suffered from the MC impact with a lower germination ratecompared to control. After 4 and 7 days of the experiment, the root and shoot of both plants were shorter uponMC incubation and the higher MC concentration applied, the shorter length of root and shoot was. The WW oflettuce and carrot seedling was significantly reduced in exposures to MC at the concentrations of 10 and 100?g/L. This study confirmed the potent toxicity of MC from Vietnam waters at the environmental concentrationsto lettuce and carrot. Bioaccumulation and distribution of MC in the plants are suggested to investigate in thefuture. |
