The aim of this experiment was to determine the response of dill (Anethum graveolens L.) towater deficiency and salinity. In spring, dill biomass decreased with increasing water deficiencydue to a reduction in the number and mean weight of leaves per plant. The concentrations ofchlorophyll, carotenoids, vitamin C and total phenolics within the leaves were unaffected bywater stress, but the Cl, ...

in order to study the effect of irrigation water salinity on quality and quantity of sugar beet (beta vulgaris) at four growth stages, an experiment was conducted in rudasht salinity and drainage research center from 2004-2006. in this experiment, 11 different water salinity treatments and three sugar beet cultivars (ic, 7233 & 7233-p29*msc2) were considered using split plot design based on ran...

Expression patterns of four candidate AREB/ABF genes and four DREB/CBF genes were evaluated in leaf and root tissues of five grape varieties ('Qalati', 'Kaj Angoor', 'Sabz Angoor', 'Siahe Zarghan', 'Bidane Safid') with differential response to drought stress. Among the AREB/ABF genes, AREB1 and ABF2 showed up-regulation in response to drought stress in leaf and root tissues of all varieties whi...

A field experiment was carried out to study the response of presoaked faba bean seeds (Vicia faba cv. Misr 2) in freshly prepared ascorbic acid (50 ppm) or distilled water (control) for 4 hrs at natural environmental conditions, to salinity stress. NaCl treatments caused a reduction in all productivity and yield parameters as compared with control, particularly at high NaCl level (150 mM), wher...

Challenged by the low salinity, 4 parts per thousand (4 ppt), for 72h, the survivals of swimming crabs (Portunus trituberculatus) were collected as the screened group (SG, tolerant to low salinity). Aiming at identifying the mechanism of low salinity tolerance, quantitative real-time PCR was employed to investigate the expression profiles of 4 HSP genes (HSP60, HSP70, HSP90-1, HSP90-2) in the h...

Halorhabdus utahensis, Natronomonas pharaonis, Haloferax sulfurifontis and Halobaculum gomorrense were grown at salinity values between 10% and 30% NaCl (w/v). The strains represent four haloarchaeal genera and have a range of salinity optima. Analysis of core membrane lipids of each strain using gas chromatography–mass spectrometry (GC–MS) revealed structures consistent with saturated, unsatur...
