CLONAL INTEGRATION AND THE EXPANSION OFPHRAGMITES AUSTRALIS

Ecological Applications, 2000
The recent expansion of the reed Phragmites australis in western Atlantic salt marshes has become a conservation concern. Historically, Phragmites was restricted to the terrestrial border of marshes, but now it aggressively invades lower elevations.

Concentration responses to organochlorines in Phragmites australis

Environmental Pollution, 2012
Phragmites australis shows potential for the phytoremediation of chlorinated chemicals. Also there has been some attempt to determine the phytotoxic effects of organochlorines (OC). This study reports for lindane (HCH), monochlorobenzene (MCB), 1,4-dichlorobenzene (DCB) and 1,2,4-trichlorobenzene (TCB), a no-observed-effect-concentration (NOEC(7d ...

The flavonoids of phragmites australis flowers

Phytochemistry, 1980
Abstract The major flavonoid constituents of Phragmites australis flowers are the C-glycosylflavones swertiajaponin, isoswertiajaponin and two new O-glycosides, the 3′-O-gentiobioside and the 3′-O-glucoside of swertiajaponin. Two unusual flavonol glycosides, rhamnetin 3-O-rutinoside and rhamnetin 3-O-glucoside, were also characterized from the same ...

Physiological and anatomical characterisation of Phragmites australis leaves

Aquatic Botany, 2002
Abstract The anatomy, biochemistry and physiology of Phragmites leaves have been investigated. Biochemical and physiological measurements indicate that Phragmites australis leaves have a C 3 mechanism of carbon fixation. However, structural and ultra-structural observations of young leaves are more reminiscent of a C 4 -like anatomy. In addition,

Phragmites australis and silica cycling in tidal wetlands

Aquatic Botany, 2007
Tidal marshes have recently been shown to be important biogenic Si recycling surfaces at the land–sea interface. The role of vegetation in this recycling process has not yet been quantified. In situ and ex situ decomposition experiments were conducted with Phragmites australis stems.

Copper tolerance, uptake and accumulation by Phragmites australis

Chemosphere, 2003
Copper (Cu) uptake and accumulation of five populations of Phragmites australis growing in two mine sites (Parys Mountain, Wales, UK and Plombières, Belgium) contaminated with Cu and three 'clean' sites (Felixstowe, UK; Wisbech, UK and Mai Po, Hong Kong) were studied under field and glasshouse conditions. Cu tolerances in these populations of seedlings

The Effects of Salinity and Flooding on Phragmites australis

The Journal of Applied Ecology, 1992
1. Phragmites australis buds with attached rhizomes were planted in PVC tubes and grown under various salinity and flooding conditions in a greenhouse for one growing season. 2. P. australis buds did not emerge from cores flooded to the soil surface, regardless of salinity, indicating a possible lack of oxygen transport to below-ground structures.

Effects of salinity on the growth of Phragmites australis

Aquatic Botany, 1997
Abstract The field salinity tolerance of Phragmites australis was evaluated by investigating 27 natural reed habitats along the eastern and western coasts of Jutland, Denmark. Die-back took place in the lower fringe of stands, before the onset of flowering, at sites where soil water salinities were higher than 15‰ within the rooting depth.
