the biosorption of hexavelent chromium from saline solutions by posidonia oceanica, a marinebiomass, was studied as a function of ph, initial chromium (vi) and salt (nacl) concentrations in batchsystem. the sorbent exhibited the maximal chromium (vi) uptake at ph 2 regardless of the presence ofincreasing salt concentration. equilibrium uptake increased with chromium (vi) concentration up to 250...
growth response and ion distribution of two canola varieties to different potassium to sodium ratios
rapeseed (brassica napus l.) is a crop relatively tolerant to salt. the effect of different ratios of nacl/kcl was studied in two cultivars (hyola308 and kristina) of rapeseed in 2002. canola seedlings were grown in hoagland’s solutions, which were salinized by different ratios of nacl/kcl. the treatments or kcl:nacl ratios were 0:0 (control);10:10; 20:0 (total added salt or tas=20 mol.m-3), 0:...
To examine the response of three rapeseed varieties to salinity stress, a pot experiment was conducted in a glasshouse using a factorial experiment based on a randomized complete block design with three replications. Three levels of NaCl (0, 100 and 200 mM NaCl) were imposed as the salinity treatments at root establishment (leaf 4) stage. In this study, sodium (Na+) and potassium (K+) concentra...
Enlarged root systems that extend into the salt affected soil improve water and nutrient capture by plants and can increase plant productivity. In order to examine root system characteristics of four bread wheat cultivars contrasting in salt tolerance (Arg, Ofoq, Tajan and Morvarid) a greenhouse experiment was conducted with applying two salinity levels (0 and 150 mM NaCl) on plants grown in PV...
Salt stress is one of the main abiotic stresses for rice that causes negative effects on its growth and productivity. In present study, effects of salt stress on differential gene expression of some genes which are responsible in salt stress were investigated in two rice tolerant and sensitive genotypes (FL478 and IR29) by applying cDNA-AFLP technique. Among the TDFs (Transcript Derived F...
