Effects of Monosulfuron on Mixotrophic Growth and Photosynthetic Pigments of Auabaena flosaquae Breb. Exposed to Different Light Intensities

摘要

Exposed to three light intensities, the six concentrations of monosulfuron tested can significantly inhibit the growth of Auabaena flos-aquae in a dose-dependent manner. The herbicide monosulfuron appeared to have different effects on the synthesis of photosynthetic pigments. A. flos-aquae had different degrees of sensitivity to monosulfuron with the most sensitive light intensity being 4000-lux followed by 3000-lux and 2000-lux.
