Salinity is one of the major environmental constraints affecting agriculture in regions world. This study was conducted to evaluate effect exogenous nitric oxide (NO) treatments on two chickpea cultivars (Cagatay and Inci) under salt stress conditions. Different NO doses (0. 75 100 μM sodium nitroprusside (SNP)) as an source were applied plants grown saline (presence 50 mM NaCl) nonsaline In th...

Wheat growth, development and yield are severely affected by a wide range of abiotic stresses, salt stress is vital increasing stress. Salicylic acid (SA) phenolic phytohormone involved in plant physiological processes. Hence, we have conducted an experiment to explore the roles exogenous SA mitigating two wheat genotypes. There were eight treatments comprising (i) control, (ii) 0.5 mM SA, (iii...

in wheat na+ exclusion and k+/na+ have shown to be associated with salinity tolerance, therefore in order to identify qtls with additive effect for na+ and k+ concentration traits in roots and shoots of wheat, 319  bread wheat recombinant inbred lines (ril f7), derived from a cross between roshan cultivar (salt tolerant) and falat cultivar (salt sensitive), along with their parents and 2 checks...

Salinity is a major limitation ecological factor for plant development in arid and semi-arid regions. The ionic imbalance, deficiency of nutrients and degradation of plant metabolites are caused by saline conditions, are affected by the reduction ratio of potassium (K) then sodium (Na). In this research foliar applications of humic acid (HA) for improve the absorption of K under salt stress was...

abstract in order to study salt stress, calcium and potassium effects and type of application on sorghum plant, a field experiment was arranged in randomized complete block in split plot design at the research field of center of excellence for special crops, ferdowsi university of mashhad at 2008. experimental treatments were included two levels of salinity (5 and 10 ds.m-1) as main plots and f...

soil salinity affects ions concentrationss of plant tissues and this may alter the merits quality of medicinal plants. experiments were conducted during 2003 at the the isfahan university of technology campus, isfahan, iran, to assess the effects of five soil salinity levels (3.2, 3.6, 4.5, 5.4 and 7.5 ds m-1) on na, k, and ca contents of borage and echium. each plant species was studied in a s...

The goal of this research project was to determine the water transport behaviour of earlywood versus latewood in the trunk of 21-year-old Douglas-fir [Pseudostuga menziesii (Mirb.) Franco] trees. Specific conductivity (k(s)) and the vulnerability of xylem to embolism were measured on a single growth ring and in a subset of earlywood and latewood samples within the same ring. Earlywood/latewood ...
