What Is Water Hyacinth?

Decent Essays
Eichhornia crassipes commonly referred to as Water Hyacinth is a free floating weed that is commonly found sharing a habitat with S. molesta (Shanab, Shalaby, Lightfoot, El-Shemy 2010). When temperature, radiation, and sunshine duration increase the density of E. crassipes increase and this causes large amounts of phenolic allochemicals in the water where the weed is located (Shanab et al. 2010). Placing the phenolic allochemicals in the water could have a purpose of helping water hyacinth to invade the bodies of water in a fast pace (Shanab et al. 2010). Water hyacinth is known as one of the top ten weeds in the world (Shanab and Shalaby 2012). The allelochemicals co incur with the environment, and E. crassipes release fatty acids, polyphenols,…show more content…
is commonly known as duckweed and is thalloid that floats on top of the bodies of water connected by small roots (Zhao 2012). This floating plant collectively shares bodies of water with S.molesta and E. crassipes. Lemna sp. retrieves polluting nutrients like phosphorus and nitrogen from its habitat (Zhoa 2012). Duckweed contains high sources of starch and ethanol located in the cell wall of the leaves (Zhoa 2012). The cell wall is also containing significant amount of pectin and cellulose (Zhoa 2012). Freshwater ecosystems are fragile systems that are enormously affected when invasive species alter their ecosystems. With the invasive species Salvinia molesta in a body of water this causes disturbances and causes degradation in the freshwater ecosystems. With water ways being destroy by S. molesta this a habitat problem but can also be a reactional problem. The present study investigates if Eichhornia crassipes and Lemna sp. extracts affect Salvinia molesta. The affect will be determined by S. molesta growth and health. Based on the observation, it is hypothesized that S. molesta growth will not be affected by the extractions of Eichhornia crassipes and Lemna sp. The affect of the extractions will be determined by creating the extraction of plant material at different levels of concentration and adding diH2O. The wet weight of the S. molesta was recorded before the plant was placed in containers and after the plant was taken out of the containers, and the results
