Secondary metabolites of Ceratophyllum demersum
Hydrobiologia, 1995Ceratophyllum demersum L. is abundant in European rivers and ponds and produces a large amount of biomass. Almost nothing is known about its secondary metabolites. We isolated two flavonoid glycosides and identified one of them an apigenin-7-O-glucoside. Seven sterols, the main one sitosterol, were also identified. Volatile compounds contained mainly n-

Ceratophyllum demersum-An accretion biotool for heavy metal remediation
Science of The Total Environment, 2022Freshwater habitats are under serious threat due to the diverse pressures of development and restoration of these ecosystems is an important challenge in the present era. With a number of scientifically advanced methods available for restoration of these systems, phytoremediation finds its unique space as an ecologically sustainable technique.

Variation of Ceratophyllum Demersum in Eastern Kansas
Transactions of the Kansas Academy of Science (1903-), 1951Field observations in the state reveal that Ceratophyllum demersum L. is a much more common plant than our records show. Gates (1940) lists the plant from eight scattered counties. The writer has, however, found the species in many Kansas counties and feels certain that it occurs throughout the state in suitable habitats.

Hormonal interactions in Ceratophyllum demersum
Aquatic Botany, 1982Ceratophyllum demersum L. is a submerged aquatic macrophyte without roots. It occurs in winter in the dormant form and in summer in the active form. The effect of application of mixtures of indole acetic acid (IAA), abscisic acid (ABA) and gibberellic acid (GA3) on subsequent growth after treatment in the quiescent stage was studied.

Ammonia stress on the carbon metabolism of Ceratophyllum demersum
Environmental Toxicology and Chemistry, 2014Abstract In the present study, carefully controlled pH ranges (7 and 9) were used to distinguish between the effects of un-ionized NH3 and the NH4+ ion. The objective was to find the effect of different total ammonia nitrogen concentrations and pH values on the carbon metabolism of Ceratophyllum ...

Growth Substances and Dormancy in Ceratophyllum demersum
Physiologia Plantarum, 1979Abstract Ceratophyllum demersum L. occurs in winter in the dormant form, in summer in the vegetative form. Factors that affect growth and dormancy in Ceratophyllum were studied. After several weeks of severe winter conditions the plants changed from dormant to quiescent state.

Effect of ammonia stress on nitrogen metabolism of Ceratophyllum demersum
Environmental Toxicology and Chemistry, 2015Abstract The objective of the present study was to determine the effect of total ammonia N concentration and pH on N metabolism of Ceratophyllum demersum and to evaluate stress as a result of inorganic N enrichment in the water column on submerged macrophytes.

Ceratophyllum demersum (coontail).
2021Abstract C. demersum is a cosmopolitan submerged aquatic species that has probably already invaded most of its potential exotic range. It has the advantages of being a perennial surviving well over-winter in deeper water and by growing both by asexual reproduction of broken or complete stems and by sexual reproduction of very many ...
