In order to understand the response of tobacco to salt stress, antioxidant enzyme activities, plant biomass and ion content were analyzed in two oriental tobacco genotypes (Basma 31 and SPT 406). Tobacco plants were exposed to 0, 50, 100, 150 and 200 mM NaCl for 12 days. The fresh and dry weight as well as shoot and root length of Basma 31 were greater than those of SPT 406 under increasing sal...

The use of sprouts in the human diet is becoming more and more widespread because they are tasty and high in bioactive compounds and antioxidants, with related health benefits. In this work, we sprouted rapeseed under increasing salinity to investigate the effect on free and bound total phenolics (TP), non-flavonoids (NF), tannins (TAN), phenolic acids (PAs), and antioxidant activity. Seeds wer...

Small unilamellar vesicles composed of phosphatidylserine (PS) and cholesterol at various ratios were employed in studying the effect of cholesterol on Ca2+-induced vesicle aggregation and fusion using the Tb/dipicolinic acid assay. The leakage of preencapsulated Tb3+ was also measured. The analysis of the data provided estimates for the rate of aggregation C11, and the rate of fusion per se, f...

Background and objective: This study was conducted to determine the effect of NaCl on growth, antioxidants (superoxide dismutase, proline), maximum quantum yield, chlorophyll contents Pseudolysimachion pusanensis.Methods: Five levels concentrations (0, 50, 100, 200, 400 mM) were used for treatment. Results: The growth according highest at 50 100 mM, but root declined before top from 200 mM or h...

An in vitro line of transformed BALB/3T3 mouse fibroblasts was exposed to a 100 mM increase in the NaCl concentration of its growth medium. The rate of growth, as measured by the incorporation of tritiated thymidine, decreased almost 100-fold during the first 24 h of exposure to the hyperosmotic medium and then increased approximately 10-fold during the second 24 h of exposure. Cell counts of c...

Within the scope of this study, effects L-Glutamic acid (L-GLU: 250 mg L-1, 500 L-1) treatments on morphological and biochemical characteristics SC2121 tomato variety under salt stress (50 mM, 100 200 mM NaCl) were compared. The results obtained from leaves fruits found to peak at 500GLU, 50NaCl-500GLU, 250GLU, 200NaCl-500GLU, whereas their lowest values achieved with doses 200NaCl, 200NaCl-250...

in order to evaluate the effect of different levels of salinity and three nitrogen nutrition on biochemical reactions and changes in dry weight of shoot and root on psyllium (plantago ovata f.), a glasshouse experiment in a complete randomized design with three replications in 2009 at university of zabol was conducted. salinity treatments in this experiment were 0, 100 and 200 mm of nacl and ni...
