Eutrophication is a serious problem occurring in ponds or estuaries where fish culture is practised. A possible solution to this problem is to raise oysters in an integrated culture with fish to improve water clarity and to help remove excess nutrients. In order to determine the effects that cultured oysters have on the environment, an experimental study was performed in the Moothakunnam region...

abstract a greenhouse experiment was conducted to study the effects of soil copper (cu) and salinity application on photosynthesis parameters, enzyme activity and anatomical structure of two pistachio cultivars. a factorial greenhouse experiment was carried out as completely randomized design with three replications. treatments consisted of four cu levels (0, 2.5, 5, and 7.5 mg kg-1soil as cuso...

The effect of salinity on the photoinduced toxicity of waterborne fluoranthene to larvae of the grass shrimp (Palaemonetes pugio) and tubificid oligochaete worms (Monopylephorus rubroniveus) was studied in a laboratory system under simulated sunlight. In the grass shrimp toxicity tests, five concentrations of fluoranthene (0, 3.6, 7.3, 13.8, and 29.0 microg/L) and four salinities (6.9, 14.5, 21...

fenugreek is one of the important medicinal plant that used in the pharmaceutical industry. in order to investigate the effects of salinity stress on relative water content, membrane stability, total chlorophyll, sodium, potassium, sodium to potassium ratio and proline, a factorial experiment was conducted in a completely randomized design with three replications in 2013. experimental treatment...

quinoa (chenepodium quinoa willd) is a grain-like crop which has a high production potential in iran. due to its seeds high nutritional value, it is compared with milk by the fao. in order to study the effects of temperatures on seed germination of quinoa seeds under salinity stress conditions, an experiment was conducted in seed lab of the university of tehran in karaj. temperatures regimes in...

Salinity in soil and irrigation water is one of the major factors that limit crop productivity. The effects of salinity on growth, lipid peroxidation, the antioxidant defence system and changes in artemisinin content were studied in Artemisia annua L. Salinity treatments were established by adding 0, 50, 100, 150 and 200 mM of sodium chloride (NaCl) to the soil. Salt stress negatively affected ...

The objective of this paper was to study the effects of two strains of isolated plant growth-promoting rhizobacteria (PGPR) on physiological and biochemical changes of wheat leaves under salinity conditions. The sterilized seeds were soaked in distilled water (control) and Nutrient Broth liquid medium of Enterobacter cloacae and Bacillus cereus (inoculated treatment) for 2 hours. After 10 days ...

in order to investigate the effect of different ratios of ammonium: nitrate on the photosynthesis and fatty acid composition in canola (brassica napus l.) under different levels of salinity, an experiment was conducted as a factorial based on complete randomize design at agricultural research center in east azerbaijan in 2010. the first factor was different ratios of nitrogen sources to ammoniu...
