Abstract

The aim of this research is to evaluate and analyze the influence of different degrees of salt stress on the tolerance of Australian wheat lines having characteristics derived from wild types in comparison with a local cultivar welladapted to Anatolian conditions under controlled conditions. In the research, the two lines, namely AU5924 and AU5907, adapted to Australian conditions harbor HKT1;4 and HKT1;5 loci and Bayraktar 2000 cultivar used as genetic material. In our study, a trial plan with four replicates and two salt treatment doses (0 mM control group and 200 mM stress group) was designed. The samples were collected for elemental analysis, measuring physiological parameters as well as determining proline content after the appearance of stress symptoms. In this respect, (K), known to play an important role in enhancing stress tolerance, was found to be higher in HKT-containing lines in comparison to Bayraktar 2000. HKT genes could improve the production of Anatolian varieties. While the dry weight of the genotype Bayraktar 2000 was higher than the lines checked, the proline content of line 5907 was lower and the potassium and (K/Na) ratio decreased. These parameters effectively increased the dry weight under salt stress. However, the line 5907 demonstrated the best tolerance among all analyzed genotypes.

Investigation of Foliar L-Glutamic Application on the Resistance to the Capacity of the SC2121 Tomato Variety (Solanum lycopersicum L.) to Long-Term Salinity Stress

“…In Türkiye, 1.5 million hectares of land face salinity problems, and 60% of these areas are salty, 19.6% moderately saline, 0.4% moderately alkaline, and 12% mildly saline (Gursoy, 2022). Salinity influences plant morphologically, physiologically, and biochemically, and lead to serious losses in yield and quality (Tuncer, 2017;Can et al, 2021). It was proven that physiological reactions promoting growth and development such as photosynthesis, respiration, nitrogen and carbohydrate metabolism, soil-waterplant relations, and cell cycle are suppressed due to salinity stress (Sadak et al, 2014;Gursoy, 2022).…”

“…It was proven that physiological reactions promoting growth and development such as photosynthesis, respiration, nitrogen and carbohydrate metabolism, soil-waterplant relations, and cell cycle are suppressed due to salinity stress (Sadak et al, 2014;Gursoy, 2022). In the studies aiming to solve the salinity problem, methods such as 1) reclamation of saline soils, 2) traditional breeding methods, modern molecular biology methods, and 3) selection and development of salinity-resistant species and varieties are primarily used (Turhan and Şeniz, 2010;Can et al, 2021). The first option is expensive and difficult, the second option is time-consuming, and the methods obtained cannot guarantee genetically modified products.…”

Determination of The Effect of Salicylic Acid Application on Salinity Stress at Germination Stage of Bread Wheat

“…Among abiotic stresses, salinity causes numerous biochemical and physiological damages in crop plants and ultimately deteriorates the grain yield and quality (Can et al, 2021). Salinity stress causes osmotic stress and ion toxicity by increasing the assimilation of Na + ions and decreasing the Na + /K + ratio due to low osmotic potential in plant roots.…”
