this study was conducted to find out the influence of in vitro salinity on growth parameters shoot length, number of leaves, number of new buds, the chlorophyll, chlorosis and necrosis and absorption of sodium, chloride, potassium, nitrogen and phosphorus of pear (pyrus communis cv. dargazi) in vitro propagated shoots. the experiment was conducted as a complete randomized design with 5 salinity...
In order to evaluate the effects of salt stress and putrescine on some morphological and biochemical traits and pigment content of pot marigold plant, an experiment was conducted under greenhouse conditions based on completely randomized design, using four levels of sodium chloride (1, 3, 6 and 9 dS/m) and three levels of putrescine (0, 1 and 2 mM). Sodium chloride was applied on the soil, whil...
Substrate and product inhibition of hydrogen production during sucrose fermentation by the extremely thermophilic bacterium Caldicellulosiruptor saccharolyticus was studied. The inhibition kinetics were analyzed with a noncompetitive, nonlinear inhibition model. Hydrogen was the most severe inhibitor when allowed to accumulate in the culture. Concentrations of 5-10 mM H(2) in the gas phase (ide...
In order to investigate the interaction effect of salinity and supplementary calcium nitrate on growth, quantitative and qualitative attributes of flowers and mineral composition of Rosa hybrida ‘Ilona’, a factorial experiment was carried out in completely randomized design with three replications. Treatments consisted of four sodium chloride rates (0, 5, 10 and 20 mM sodium chloride) and four ...
To determine the extent to which baroreceptor function is a determinant of salt-dependent hypertension, we studied the cardiovascular and renal responses to increasing dietary sodium chloride in sinoaortic-denervated (n = 9) and sham-denervated (n = 9) Sprague-Dawley rats. Rats were instrumented with an arterial catheter for measurement of arterial pressure and were individually housed for dail...
abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...
sulforaphane is a strong anticarsenogen compound which is produced in broccoli. it seems salt stress improves sulforaphane production via systemic acquired resistance. to obtain suitable salt concentration and for having more content of sulforaphane with controlling germination percentage, nacl in 5 levels 0, 50, 100, 150, 200 mm (0, 4.53, 9.125, 13.68, 18.25 ds/m ) and salicylic acid in 3 leve...
Bromus danthoniae Trin. is an annual grass species that is well adapted to harsh climates and could be considered as an important genetic resources for tolerance to environmental stresses such as salinity. In this study, 24 genotypes collected from Ilam, Kurdistan, Kermanshah (non-saline areas) and West Azerbaijan (saline area: shores of Uremia Salt Lake) provinces of Iran were investigated at ...
The interactive inhibitory effects of pH and chloride on the catalysis of laccase from Trametes versicolor were investigated by studying the alteration of inhibition characteristics of sodium chloride at different pHs for the oxidation of 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid). At pH 3.0, the addition of sodium chloride (50 mM) brought about a 40-fold increase in Km(app) and a 4...
