Dormancy and foliar density regulation in Thalassia testudinum

Aquatic Botany, 2000
Abstract The hypothesis that the tropical seagrass, Thalassia testudinum from the Puerto Morelos reef lagoon (Mexican Caribbean) has a dormant apical meristem bank (as opposed to a dormant axillary meristem bank) was investigated by morphological and anatomical analyses of vertical shoot apices.

Some Chemical Constituents of Turtle Grass, Thalassia testudinum

Bulletin of the Torrey Botanical Club, 1959
Primary biological productivity in the coastal waters of Puerto Rico is based upon the synthetic processes of phytoplankton, benthic algae, mangroves, corals and the turtle grass, Thalassia testudinum. A considerable portion of the total production of organic matter in this region appears to be contributed by the large beds of Thalassia, widely ...

Effects of heavy rainfall on Thalassia testudinum beds

Aquatic Botany, 2007
In December 1999 heavy continuous rains that lasted one week affected the Venezuelan coastline. At Morrocoy National Park, a large marine reserve, rainfall values surpassed previous 32-year records and led to a decrease of salinity to 3 psu, which lasted for over a month at some locations.

Changes in trace metals in Thalassia testudinum after hurricane impacts

Marine Pollution Bulletin, 2011
Major hurricanes Emily and Wilma hit the Mexican Caribbean in 2005. Changes in trace metals in the seagrass Thalassia testudinum prior to (May 2004, 2005) and following passage of these hurricanes (May, June 2006) were determined at four locations along a ≈ 130 km long stretch of coast.

Vegetative Branching in Thalassia testudinum (Hydrocharitaceae)-A Correction

Botanical Gazette, 1972
Horizontal scale-bearing rhizomes in Thalassia produce, at fairly regular but distant intervals, lateral branches which develop into erect, leafy shoots. These branches are leaf-opposed, not axillary. Since they originate precociously and are at first equal to the main axis, it had been suggested that they are the result of an equal dichotomy of the ...

ABCG2/BCRP interaction with the sea grass Thalassia testudinum

Drug Metabolism and Personalized Therapy, 2015
Abstract Background: The aqueous ethanolic extract from leaves of the marine plant Thalassia testudinum has shown antioxidant, cytoprotective, and neuroprotective properties. The chemical composition of this extract, rich in polyphenols, could interfere with active transport of drugs out of the cell and circumvent the ...

Factors affecting the reproductive ecology of Thalassia testudinum (Hydrocharitaceae)

Aquatic Botany, 1987
Abstract Morpho-anatomical studies of short-shoots of Thalassia testudinum Banks ex Konig collected in Tampa Bay, Florida from February 1979 to October 1980 ( n = 5394) demonstrated the presence of sexually reproductive short-shoots during all months, except August and September. Mean inflorescence lengths (MIL) indicated that little inflorescence

Vertical growth of Thalassia testudinum: seasonal and interannual variability

Aquatic Botany, 1994
The vertical growth of shoots of the seagrass Thalassia testudinum Banks ex Konig in four meadows, along a range of exposure to waves, in the Mexican Caribbean was examined to elucidate its magnitude and its relationship to sediment dynamics. Average internodal length varied between 0.17 and 12.75 mm, and was greatest in the meadow which experienced ...

Regrowth of the seagrass Thalassia testudinum into propeller scars

Aquatic Botany, 1997
Abstract Regrowth of turtle grass, Thalassia testudinum Banks ex Konig, into existing propeller scars and artificial cuts was studied in a mangal estuary located in Tampa Bay, Florida. Sediments from scars and cuts and adjacent grass beds were not significantly different in relation to particle size distribution and levels of calcium carbonate ...

Thalassia testudinum

2016
4.10. Development of an herbal medicine from T. testudinum Rodeiro et al. (2008a) demonstrated that T. testudinum extracts had only marginal cytotoxicity towards rat hepatocytes and did not significantly interfere with P450 enzymes. Moreover, Rodeiro et al. (2008b) demonstrated that T.
