Abstract

Background and Objectives: Due to the limited availability of suitable water resources in arid and semi-arid regions, saline water is a very important source of irrigation in these areas. Plant stimulation using magnetized water and its modulating effect on water salinity has been considered as a way to increase the quantity and quality of the crop. The aim of this study was to evaluate the root system characteristics of different wheat species under magnetic water application and salinity stress.
 
Materials and Methods: The experiment was conducted as a factorial based on a randomized complete block design with three replications in 2019 at the Research Farm of the Faculty of Agriculture, University of Tabriz. The factors included magnetized water (0 and 400 milliTesla), salinity levels of irrigation water (Control (distilled water), 3 and 6 dS/m (NaCl)), and the third factor was six wheat genotypes including diploid (Triticum monococcum), tetraploid (durum wheat cultivars Savaz, Persian, and Dehdasht), and hexaploid (bread wheat cultivars Chamran, Kohdasht).
 
Results: Under moderate and severe salinities, mean shoot biomass, crown diameter, root dry weight, root volume, K+ concentration, and the K+/Na+ ratio in roots and shoots decreased, while root area, cumulative root length, and Na+ concentration in roots and shoots significantly increased. Magnetized water mitigated salinity stress by increasing crown diameter (14.8%), root dry weight (56.4%), rooting depth (34.6%), root volume (approximately 2-fold), root surface area (67.2%), cumulative root length (75.1%), and root-to-shoot ratio (30.1%). It also enhanced K+ concentration (by 14.9% and 8.2%, respectively) and the K+/Na+ ratio (by 20.5% and 13.1%, respectively) in roots and shoots while reducing Na+ concentration in roots and shoots (by 7.9% and 9.8%, respectively). Mean measured traits showed the superiority of Kohdasht and Chamran cultivars over other wheat species across salinity levels.
 
Conclusion: Shoot and root dry weight, root volume, root surface area, total root length, root to shoot ratio, potassium concentration, and potassium to sodium ratio in roots and shoots were improved by magnetizing irrigation water. In terms of root traits and also biomass production, the superiority of Kohdasht and Chamran cultivars over other varieties under salinity stress with the use of magnetized water was evident. Therefore, in regions where access to non-saline water is not possible, the use of magnetized water and the use of resistant cultivars such as Kohdasht and Chamran, is recommended to improve wheat yield.
