Eichhornia crassipes (water hyacinth).

2021
Abstract E. crassipes, a native of South America, is a major freshwater weed in most of the frost-free regions of the world and is generally regarded as the most troublesome aquatic plant (Holm et al., 1997). It has been widely planted as a water ornamental around the world because of its striking flowers. Wherever it has encountered

Cyanide phytoremediation by water hyacinths (Eichhornia crassipes)

Chemosphere, 2007
Although cyanide is highly toxic, it is economically attractive for extracting gold from ore bodies containing only a few grams per 1000 kg. Most of the cyanide used in industrial mining is handled without observable devastating consequences, but in informal, small-scale mining, the use is poorly regulated and the waste treatment is insufficient ...

Aquatic macrophytes and Eichhornia crassipes

1982
Munro (1966) defined the shoreline habitats of Lake McIlwaine in terms of the presence or absence of aquatic macrophytes, and the major species of macrophyte where the plants were present. Relatively few areas of the lake shore were free of macrophytes (Fig.

Evapotranspiration of water hyacinth (Eichhornia crassipes)

Journal of Hydrology, 1974
Abstract From water balance measurements near the Agricultural Experiment Station at Paramaribo and on the Brokopondo Lake, the evapotranspiration of water hyacinth appeared to be respectively 48% and 44% higher than the free water evaporation. These values are much lower than could be expected based upon values given in the literature.

Eichhornia crassipes Genome sequencing and assembly

2023
Eichhornia crassipes, commonly known as common water hyacinth, is one of the most notorious weeds that cause severe damage to the economy and natural ecosystems of infested areas. Here, we assembled a chromosome-level genome for E. crassipes.

Dimeric phenalene metabolites from Eichhornia crassipes

Tetrahedron, 1992
Ten aromatic metabolites with the phenalene skeleton have been isolated as permethylated derivatives from the ethyl acetate extract of the aquatic plant Eichhornia crassipes. Beside the already described monomeric lachnanthocarpone red dimethyl ether,4,9-dimethoxy-7-phenyl-2,3-dihydro-phenalen-1-ol-O-methyl,4,9- dimethoxy-7-(4′-methoxy-phenyl)-2,3 ...

Optimization of arsenic phytoremediation using Eichhornia crassipes

International Journal of Phytoremediation, 2018
This study aimed to evaluate the pH, phosphate, and nitrate in the process of arsenic absorption by Eichhornia crassipes (water hyacinth), using the surface response methodology, in order to optimize the process. The plants were exposed to a concentration of arsenic of 0.5 mg L-1 (NaAsO2) over a period of 10 days.

Water Hyacinth Eichhornia crassipes (Mart.) Solms

2017
Water hyacinth, Eichhornia crassipes, is considered as one of the world’s worst weeds. They successfully invaded lakes, ponds, canals, and rivers. It is still rapidly spreading into many countries,influencing local environmental and agriculture cultural problems. The aim of this chapter is to summarize the effects caused by E.
