in this study, the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. aurantium, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} on orlando tangelo leaf chlorophyll content and mineral element concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) have been evaluated in completely randomized design with four replications. ...

the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. limetta, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} were evaluated on sweet lime leaf chlorophyll content and mineral concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) in a completely randomized design of four replications. budded sweet lime on the above root...

The volume of the nucleus, endoplasmic reticulum (including Golgi complex), mitochondria, and cytoplasmic ground substance was measured in rat hepatocytes by stereological methods. The Na content was also measured by flame photometry. Variations in Na content correlated significantly with variations in volume of nucleus and endoplasmic reticulum. From the correlation parameters, Na concentratio...

Compared with age-matched men, women are resistant to the hypertensive effects of dietary NaCl; however, after menopause, the incidence of salt-sensitive hypertension is similar in women and men. We recently suggested that osmotically inactive Na+ storage contributes to the development of salt-sensitive hypertension. The connective tissues, including those immediately below the skin that may se...

We previously showed an inverse correlation between membrane cholesterol content and Na-P(i) cotransport activity during the aging process and adaptation to alterations in dietary P(i) in the rat (Levi M, Jameson DM, and van der Meer BW. Am J Physiol Renal Fluid Electrolyte Physiol 256: F85-F94, 1989). The purpose of the present study was to determine whether alterations in cholesterol content ...

The Na(+), K(+) and Ca(2+) content of plasma and aortic vascular smooth muscle from normotensive and A.S.-hypertensive rats have been compared. There was no significant difference in the plasma concentrations of Na(+), K(+) and Ca(2+), or the Na(+), K(+) and water content or (3)H-inulin space of aortic tissue in the two groups.There was a marked increase in the amount of Ca(2+) in the aortae ta...

to determine the most important traits affecting root yield and sugar content in monogerm germplasm of sugar beet, 75 monogerm f1 hybrids were evaluated in three separate experments conducted in randomized complete block desing (rcb) with four replications at abdo–al–rasoul research farm, karaj in 2004. root yield, root length, root diameter, crown height, crown diameter, sugar content, α–amino...

Turfgrass nutrient uptake may be differentially affected by different salts. The objective of this study was to compare nutrient uptake in tall fescue (Festuca arundinacea Schreb.) as affected by carbonate, chloride, and sulfate under iso-osmotic, iso-Na+ strength conditions. 'Tar Heel II' and 'Wolfpack' cultivars were subjected to NaCl, Na2CO3, Na2SO4, CaCl2, NaCl+ CaCl2, Na2CO3+ CaCl2, and Na...

In order to understand the response of Lotus corniculatus to salt stress, ions content and some growth factors were analyzed in three varieties of this plant, namely, Ardebil, Karaj, and Jolfa. Lotus corniculatus plants were exposed to 0, 50, 100, and 150 mM NaCl in hydroponic condition. The amounts of anions (Cl-and NO3-) and cations (K+ and Na+) in leaves as well as shoot and root dry weights...

With a view to test how the branchial and intestinal tissues of fish, the two sites of metal acquisition, utilize the water-borne ferric [Fe(III)] iron and whether the accumulation of this form of iron influences cellular Na/K gradient in these tissues, the gills and intestines of climbing perch adapted to freshwater (FW) and acclimated to dilute seawater (20 ppt; SW) were analyzed for ouabain-...
