a solution culture experiment was conducted to evaluate the salinity tolerance of 15 tomato genotypes in hoagland’s nutrient solution with three levels of nacl (0, 75, and 150 mm). the experiment was conducted in completely randomized design with three replicates. after 30 days of imposition of salt stress, gas exchange parameters including transpiration rate, stomatal conductance, co2 assimila...
an experiment was conducted in algerian desert goats to study the effect of age and season on blood biochemical and mineral profile during different physiological stages of the goats. serum ca, mg and na levels were significantly high at birth and decreases as the age advanced. the season had a significant effect on the decreased levels of ca, mg and k and inversely on the increased levels of n...
This study was conducted to evaluate the effect of salinity on concentration of potassium (K), sodium (Na) and chloride (Cl) ions, in sweet lime budded on five citrus rootstocks, including Bakraii (mandarin x sweet lime), Volcameriana, Sour orange, Sweet lime and Mexican lime in a glasshouse, using a randomized completely design with factorial arrangement and four replications. Rootstocks had...

terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...
Drought stress is one of the most important environmental stresses in reduce of growth and plants production. Determination of resistance mechanisms to environmental stress in plant improvement is very important. In order to , experiment with osmotic potentials of PEG (zero (control), -4, -8 & -12 bar) and alfalfa genotypes was done. The selected alfalfa genotypes namely, Yazdi(tolerant), Niksh...
An experiment was designed to investigate the effect of grafting Cucumis sativus var. Super daminos on Cucurbita moschata (Rs) and Lagenaria siceraria (Lg)which is comparing with non-grafting of Cucumis sativus var. Super daminos (Rn) and self-grafting (Rc). The experiment carried out as a factorial experiment based on complete randomized design (CRD) with 4 replicates in two temperature treatm...
An experiment was conducted in Algerian desert goats to study the effect of age and season on blood biochemical and mineral profile during different physiological stages of the goats. Serum Ca, Mg and Na levels were significantly high at birth and decreases as the age advanced. The season had a significant effect on the decreased levels of Ca, Mg and K and inversely on the increased levels of N...
AbstractThis study was undertaken to better understand the probable mechanisms of salt stress tolerance induced by seed priming of salicylic acid (SA) in barley. The barley seeds were pre-soaked by SA or water and then sown under different saline watering regimes including 0.62 (tapwater), 5, 10 and 15 dS m-1 in petri dishes and trend of water absorbing, seedling growth, germination rate and pe...
dry land salinity is one of the major problems affecting agricultural products. the main consequences of plant exposure to salt stress are water deficit and ion excess, which lead to several morphological and physiological changes. in order to evaluate the effect of salinity on some physiological characteristics of 8 spring rapeseed cultivars, an experiment was conducted in the greenhouse at ya...
