Effects of NaCl on some physiological and biochemical responses in two cultivars of L. usitatissimum
Linum usitatissimum L. is one of the economically important oilseed crops and salt stress is one of the major environmental challenges affecting several physiological processes in plants. The present investigation was carried out to study the effects of NaCl on some physiological and biochemical responses in two cultivars of L. usitatissimum. Twenty-one-day-old-plants were exposed to salt stres...
Salinity stress is one of the limiting factor determining plant growth and development through negative effects on plant physiological processes. Interaction of salinity and certain plant growth regulators such as gibberellin affected physiological and biochemical responses in plants. In present research, the effects of different concentrations of sodium chloride (0, 30, 60, 90 and 120 mM NaCl)...
this study was conducted on two canola (brassica napus) cultivars, okapi a winter type and cold tolerant and rgs003 a spring type and cold sensitive. seedlings were grown in an environmentally controlled growth room with 16 h d-1 photoperiod at 22/16 °c (day/night, control). at the 4-leaf stage, half of pots were transferred to a cold growth room for 7 d at 10/3°c (day/night, cold treatment) an...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...

background: diazinon (dzn) is one of the most organophosphates (ops) insecticides that widely used in agriculture and industry. some ops are capable to produce free radicals and induce malfunction in body antioxidant systems. enzymatic and nonenzymatic antioxidants such as superoxide dismutase (sod), catalase (cat) and glutathione s-transferase (gst) and glutathione (gsh) normally counteract da...
The effect of different thiourea (TU) concentrations (10 and 20 mM) on antioxidants, protease activity and protein content with and without H2O2 (50 mM) induced stress was investigated in wheat leaves. A gradual decrease in protein content with a peak at 72 hours was observed in stressed as well as control leaves. This gradual decrease in leaf protein content at different time intervals was com...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
