Evaluation of a wetland species: Cyperus giganteus vahl (Poales – Cyperaceae), propagation and efficiency in effluents bioremediation
The Ypacarai Lake is located in the City of San Bernardino, Cordillera Department, Paraguay. This lake is part of an important system of wetlands that covers a large area and is of vital ecological importance due to its rich biodiversity and its numerous roles in the regulation of environmental adaptation and maintenance. However, in recent years this system has suffered an onslaught of pollution due to the discharge of highly contaminated effluents. It is known that this type of complex and fragile ecosystem in the face of degradation processes, such as drainage for agricultural use and civil works, which on various occasions cause alterations in its natural dynamics, such as a decrease in the capacity to regulate water quality, loss of endemic species, among countless other impacts on the environment. In this study, an endemic species of this wetland system, Cyperus giganteus, was studied, mainly addressing the best time to collect seeds for plant production, the viability of its seeds and the power of biopurification of household effluents, since it is the largest type of discharge that goes to this wetland system. In this research work, it was shown that the best time for fruit collection is the month of December, obtaining a percentage of seed germination of 72%, that in the accelerated aging test, the seed vigor is moderate, that the species Cyperus giganteus has optimal properties to reduce the pollution load of household effluents and it was demonstrated that it will be appropriate to repopulate some areas of the wetland with this species.
