Uniconazole has been used to improve starch production in plants through the regulation of endogenous hormone levels. Here, we reported the effect of this compound on the starch accumulation in a duckweed plant (Lemna aequinoctialis). L. aequinoctialis was grown in Hoagland medium supplemented with different uniconazole concentrations: 400, 800, and 1600 mg/L. The results showed that treatment with 800 mg/L uniconazole significantly increased plant growth rate, doubling time and its chlorophyll
