as sesame is a somewhat neglected crop, information concerning its response to salinity is lacking. the effects of nacl stress were studied on seven genotypes of sesamum indicum l. the 6-weeks-old sesame seedlings were treated with different nacl concentrations (0, 30, and 60 mm). the nacl caused significant decreases in fresh and dry mass of all genotypes; however responses of genotypes to the...
The effect of salinity stress on the antioxidant activity of catalase and peroxidase enzymes, relative water content, chlorophyll and carotenoid contents of eight safflower (Carthamus tinctorius L.) genotypes differing in salinity tolerance (4 salt tolerant and 4 salt sensitive) were evaluated. This study was conducted using a split plot design arranged as a completely randomized design replic...
Nowadays medicinal plants are considered as important economical plants. Recently, due to the extension of saline lands, shortage of appropriate agricultural farms and economical value of medicinal plants. There is a growing interes of identifying salt tolerant medicinal plants. A cheap time saving and reliable way for selecting proper salt tolerant plants can be achieved by culturing these pla...
salinity is a major environmental problem in arid and semi-arid areas. chickpea (cicer arietinum l.), like other legumes is sensitive to salinity. therefore, selection of genotypes to grow on saline areas is important. eleven chickpea genotypes (as sub plots) were grown in the greenhouse conditions on a medium containing different nacl concentrations (8 and 12 dsm-1) and control (hoagland solut...
density of rhizobium population in faba bean (vicia faba l.) fields of wollo area (asketema, gashana, kotem, major and sekota) northern ethiopia was studied. the highest population of rhizobia was found at major and the least at sekota regions. the native rhizobial strains isolated from the northern parts of the country tolerated a higher salt concentration (5% nacl) than the exotic rhizobial s...
short story as an important literary genre in the recent decade is focused by many of young writers and literary critical with searching structure, content , artistic techniques and cognitive phenomenon of these works , we can show quantity of using some parts of storied literature from new literal techniques of the word and also we can show the usage of native, cultural and social foundation...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
BACKGROUND : Asthma is exhibiting classical circadian fluctuations of clinical symptoms and airflow measurements, presumably influenced by the underlying airway inflammation and the endogenous cortisol secretion. The aim of our study was to examine the cellular and eosinophilic cationic protein (ECP) contents of sputum, collected andfrozen at 2 opposite time points of the day-and-night cycle, a...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
stem reserve remobilization is very important to keep the grain yield in wheat under terminal drought but the importance of this mechanism is unclear under terminal salinity. in this research stem reserve remobilization under terminal salinity were studied in greenhouse on four genotypes no14 and no49, different in remobilization, and bam as salt-tolerant and ghods as salt-sensitive cultivars. ...
