Impacts of different treatments on photosynthetic pigments in Azolla sp. plants. The photosynthetic pigments measured were chlorophyll a (Chlo a), chlorophyll b (Chlo b), and total chlorophyll (Total Chlo) (value (mg/g) ± the standard errors from three independent experiments under different treatments: organic, inorganic, and control). Different lowercase letters indicate significant differences between different treatments at p ≤ 0.05.
