The objective of present study was to evaluate the response of the mung bean seeds of ‘Sonali B1’ variety primed with chitosan in four different concentrations (0, 0.1%, 0.2% and 0.5%) under salinity stress of five different concentrations (i.e., 0, 4, 6, 8 and 12 dS*mm) and halotolerance pattern by applying Celite as matrix at three different moisture levels (5%, 10% and 20%). Improved germina...

The impact of landuse on stream salinity is currently difficult to separate from the effect of climate, as the decadal scale climatic cycles in groundwater and stream hydrology have similar wavelengths to the landuse pattern. These hydrological cycles determine the stream salinity through accumulation or release of salt in the landscape. Widespread patterns apparent in stream salinity are discu...

The effects of salinity on growth, water relations, glycinebetaine content, and ion accumulation in the perennial halophyte Atriplex griffithii var. stocksii were determined. The following questions were addressed: (1) What effect does salinity have on growth responses at different ages? (2) Is A. griffithii an ion accumulator? (3) Does A. griffithii accumulate glycinebetaine in response to sal...

Latonopsis australis is a rare Cladocera inhabiting the entire stretch of the Cochin backwaters, the largest monsoonal estuary along the West Coast of India, during the summer monsoon, but restricted to the upper reaches during the non-monsoon periods. Here, we present the results of an experimental study, which assessed the influence of salinity on the life table demography of the species at d...

BACKGROUND Several different classifications to characterize estuarine systems have been proposed. In this present paper, one of the most important estuaries in North Africa, the Oued Loukkos (Morocco), forms a case-study for proposing a systematic classification of this particular tidal estuary according to the vertical salinity gradient. FINDINGS This study, conducted using a CTD, shows tha...

The effect of salinity level and extended exposure to different salinity and flooding conditions on germination patterns of three salt-marsh clonal growth plants (Juncus subulatus, Scirpus litoralis, and S. maritimus) was studied. Seed exposure to extended flooding and saline conditions significantly affected the outcome of the germination process in a different, though predictable, way for eac...

According to the classical theories of ENSO, subsurface anomalies in ocean thermal structure are precursors for ENSO events and their initial specification is essential for skillful ENSO forecast. Although ocean salinity in the tropical Pacific (particularly in the western Pacific warm pool) can vary in response to El Niño events, its effect on ENSO evolution and forecasts of ENSO has been less...

Effect of five NaCl salinity treatments (0, 50, 100, 200 and 300 mM) given at different growth and developmental stages on total N level and in vitro nitrate reductase activity (NRA) in leaves and roots of two wheat cultivars viz., Ghods and Boolani was studied in greenhouse conditions. In response to salinity treatments, total N concentrations and NO3 assimilation rates in Ghods, a saltsensiti...

Title of Document: A COMPETITIVE INTERACTION AND DOMINANCE EXPERIMENT BETWEEN THE VEGETATIVE MARSH SPECIES PHRAGMITES AUSTRALIS AND SPARTINA CYNOSUROIDES UNDER ELEVATED NITROGEN AND SALINITY LEVELS Michelle L. Arthur, Master of Science, 2013 Directed By: Dr. Andrew Baldwin, Department of Environmental Science and Technology In recent decades the invasive plant Phragmites australis (common reed)...
