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 ...

Photosynthetic characteristics of the submerged macrophyte Ceratophyllum demersum
Physiologia Plantarum, 1986The photosynthetic and growth characteristics of Ceratophyllum demersum L. were investigated under laboratory conditions which simulated those encountered in the plants' normal environment. The carbon fixation rate of C. demersum measured with 14C at light and carbon saturation at pH 8.0 was 4.48 mg C (g ash‐free dry weight)−1 h−1. It was lower at pH 6.

Evolutionary aspects of the floral structure in Ceratophyllum
1994A number of floral features of Ceratophyllum conform with the present view on primitive angiosperm flowers and may therefore support the hypothesis of molecular systematists and palaeobotanists that the genus represents the basal clade of extant angiosperms: the flowers are minute; the organ number and phyllotaxis are highly variable — spiral ...

Charophyte occurrence in Ceratophyllum demersum stands
Hydrobiologia, 2014The hornwort Ceratophyllum demersum is a loosely attached to the bottom or free-floating vascular macrophyte, which builds dense stands in nutrient-rich waters. The hornwort stands are usually monospecific communities with a negligible contribution of other aquatic plants.
