Background: Due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. However, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. So, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s...

abstract for evaluating nacl salinity effect on some physiological and qualitative attributes of five winter canola cultivars, an experiment was conducted in a rcd base factorial in three replicates in greenhouse of east azarbaijan agricultural research center in 2008. five salinity levels as 0, 50, 100, 150 and 200 mm nacl treated as first factor on five rape seed (fornax, licord, elite, slm04...

ABSTRACT- Seed germination and early seedling growth are critical stages for plants establishment and production, particularly under salinity conditions. Exogenous application of silicon (Si) can enhance germination as well as seedling growth. In this experiment, the effect of priming with Si (0, 0.75, 1.5 and 2.25 mM sodium silicate) on seed germination and seedling growth under NaCl (0, 100 a...

introduction: almond (prunus amygdalus b.) is one of the most important crops consumed as a dry fruit and it is mainly adaptable to arid and semi-arid regions mostly suffering from salinity stress (8). soils with dry humidity regime are dominant in iran and in the world at large and mostly include regions with more evaporation than precipitation. this in turn leads to increased salinity of the ...

among abiotic stresses, salinity has been increasing over the time for many reasons like using chemical fertilizers, global warming and rising sea levels. under salinity stress, the loss of water availability, toxicity of na+ and ion imbalance directly reduces carbon fixation and biomass production in plants. k+ is a major agent that can counteract na+ stresses, thus the potential of plants to ...

The influence of exogenous application of glycine betaine (GlyBet) was examined on photosynthetic pigments and ions concentration of safflower under salinity stress conditions. The experiment was performed in a randomized complete block design arranged as a factorial with three replications. Salinity treatments (0, 50, 100, and 150 mM) were applied using sodium chloride (NaCl). GlyBet (0, 10, 3...

the types of scion-rootstock compound and level of salinity affect on growth characteristics and concentration of nutrition elements of almond leaves and roots. in order to evaluate the effect of salinity stress on vegetative traits and concentration of nutrition elements of leaves and roots almond genotypes, a experiment was carried out with two factors; cultivar in four levels including ‘shah...
