Antialgal ent-labdane diterpenes from Ruppia maritima

Phytochemistry, 2000
Seven ent-labdane diterpenes have been isolated from Ruppia maritima. The structures 15,16-epoxy-ent-labda-8(17),13(16),14-trien-19-al; 15,16-epoxy-ent-labda-8(17),13(16),14-trien-19-ol acetate; methyl 15,16-epoxy-12-oxo-ent-labda-8(17),13(16),14-trien-19-oate; 15,16-epoxy-ent-labd-8(17),13E-dien-15-ol and 13-oxo-15,16-bis-nor-ent-labd-8(17)-ene have ...

Two New Polyhydroxylated Sterols from Ruppia maritima

Natural Product Letters, 2001
Two new sterols have been isolated from the aquatic plant Ruppia maritima and their structures were established as (24R) ergosta-8,22-diene-3 beta,6 beta,7 alpha-triol (1) and (24R) ergosta-8(14),22-diene-3 beta,6 beta,7 alpha-triol (2) on the basis of spectroscopic analysis.

Effects of tributyltin (TBT) on the seagrass Ruppia maritima

Marine Pollution Bulletin, 2004
The effects of tributyltin (TBT) on the seagrass Ruppia maritima were studied in two growth experiments. Plants were sampled at stations in Odense Fjord and Lunkebugten, Denmark, and replanted in reference sediment without TBT, reference sediment spiked with TBT, and in impacted sediment sampled in the highly TBT contaminated (7-57 microg kg (-1) dw ...

Floral development of Ruppia maritima var. maritima

Canadian Journal of Botany, 1974
A hyaline, unvascularized sheath envelops a portion of the inflorescence near maturity. Though resembling an appendage of the main axis, in early ontogeny it develops as a prophyll of the renewal growth apex below the inflorescence. Two flowers develop on the inflorescence axis, subopposite each other.

Salinity Effects on Ruppia maritima L. Cultured In Vitro

Botanica Marina, 1993
Salinity effects were tested on rhizome growth and rooting of Ruppia maritima L. (Potamogetonaceae) cultured in vitro. In three serial 4 week experiments, production of new rhizome nodes was greatest in half strength Murashige and Skoog media prepared with distilled water (0‰) or 5‰ artificial seawater, compared to growth in media made with 10, 15 and ...

Effects of salinity changes on growth of Ruppia maritima L.

Aquatic Botany, 2003
Abstract The ability of Ruppia maritima L. to tolerate moderate salinity changes was determined in a greenhouse study. While R. maritima has been shown to survive in salinities from 0 to 70 ppt, it has been suggested that changes in salinity alone may be detrimental. We tested the hypothesis that along the northern shore of the Gulf of Mexico, R.

Effect of sulfate level on selenium uptake by Ruppia maritima

Chemosphere, 1995
Abstract Ruppia maritima (wigeongrass), the dominant aquatic macrophyte in the agricultural drainage evaporation ponds of the Central Valley of California, is a food source for various waterfowl and shorebirds. Whole-plant uptake and accumulation of selenate (SeO4−2 or Se+6), selenite (SeO3−2 or Se+4), and seleno-methionine (Se−2) by R. maritima from

Note on organic dormancy of estuarine Ruppia maritima L. seeds

Hydrobiologia, 2008
Information on seed dormancy is one of the primary requirements for successful seedling propagation of submerged aquatics and seagrass. Studies on Ruppiamaritima seed germination have been done, but the presence, requirements, and the types of dormancy have not been well understood.
