Appraising the stress responses in Azolla filiculoides elicited by short-term exposure of phenol

Phenolic compounds comprise one of the major water pollutants. Aquatic plants are mainly affected by the toxic effects of these pollutants. In this purview, the present study attempted to study the effect of phenolic compounds on a floating fern - Azolla filiculoides, which commonly grows in stagnan...
