Morphological Characteristics of Water Hyacinth (Eichhornia crassipes) and Duckweed (Lemna minor) in different conditions of municipal wastewater in the Central Rainforest, Peru

Abstract

The water pouter and duckweed are aquatic macrophyte plants native to the Central Jungle with a great capacity for adaptability to areas with high nutrient content, hence their phytoremediation potential. This study evaluated the tolerance of the two aquatic plants to different conditions of municipal wastewater (ARM), which are discharged into the Garou River of the city of Chanchamayo, for this purpose the morphology of the plants was verified. For this purpose, five different treatments were established, identified as T1 (Water hyacinth + clean water), T2 (Water hyacinth + wastewater), T3 (Duckweed + clean water), T4 (Duckweed + wastewater). and T5 (control or control group) during a period of 20 days. The results showed that the treatment (T2) has variance and better performance in pH (p > 0.0001104) and height (p > 0.001072). It is concluded that the plant Water hyacinth is more efficient for its adaptability in waters with extreme conditions.
