An efficient in vitro plantlet regeneration of Ceratophyllum
demersum L., an important medicinal aquatic plant.
It should be noted that one of the characters uniting Ceratophyllum
and Chloranthaceae, one stamen per flower, depends on the assumption that the multistaminate male structures of Ceratophyllum
are spikes of unistaminate flowers that lack subtending bracts, rather than flowers with numerous stamens.

demersum)," Bioresource Technology, vol.
It is notable that among the hydrophytes mainly the frequency of the plants of sheltered habitats, such as Spirodela, Hydrocharis, Lemna, Nuphar, Ceratophyllum
, Sparganium, Stratiotes, and Elodea increased (Table 3).
We studied three shallow lakes, which differ in their regime: el Triunfo, a clear vegetated shallow lake with abundant submerged vegetation (mainly Ceratophyllum
demersum) and low phytoplankton abundances (35[degrees]51S, 57[degrees]52'W); El Burro, a turbid shallow lake with high abundances of phytoplankton (35[degrees]42'S, 57[degrees]55'W) and Yalca, an inorganic turbid shallow lake with high amounts of suspended solids (35[degrees]35'S, 57[degrees]55'W).

Worldwide fewer than 20 of approximately seven hundred aquatic plant species are considered as major weeds, of these economic important weeds were Eichhornia crassipes (water hyacinth), Pistia stratiotes (water lettuce), Salvinia nymphellula (water fern), Ceratophyllum
), Tyha australis (cattail), Nymphea lotus (waterlily), Cyperus papyrus (reed), Vossia cuspidata (vossia) and Phragmites karka (reed) have been incriminated as weeds of the aquatic systems in Nigeria (Hutchinson, G.E., 1975).
These aquatics (Ceratophyllum
demersum, Najas sp., and Potamogeton nodosus) are common species of many aquatic habitats in Illinois (Vogel and Ebinger 1979, Dolbeare and Ebinger 1974).
La vegetacion asociada a los complejos cenagosos de los departamentos de Cesar y Cordoba fue caracterizada por Rangel-Ch (2010) y Cortes-C & Rangel-Ch (2013), quienes describieron una zonacion con punto de inicio en la cubeta de agua, en la que se refirieron a la comunidad de plantas acuaticas sumergidas con Utricularia foliosa L., Ceratophyllum
demersum L., y Najas arguta Kunth, a la comunidad de acuaticas flotantes con Eichhornia crassipes (Mart.) Solms, Eichhornia azurea (Sw.) Kunth, Pistia stratiotes L., Salvinia auriculata Aubl., Limnobium laevigatum (Humb.
Dissolved natural organic matter (NOM) impacts photosynthetic oxygen production and electron transport in coontail Ceratophyllum
Myriophyllum has been replaced by Ceratophyllum
, Lemnaceae, and Typha, which prefer a eutrophic condition.
Commonly occurring floating and submerged plants have included duckweed (Lemna spp.) and hornwort (Ceratophyllum
