Abstract
Objective: Study the effects of Azosperlium and nanoparticles (silicon and zinc) on grain yield and some traits of Triticale under salinity stress, an experimental factorial was conducted as a randomized complete block design with three replications in the research greenhouse of the University of Mohaghegh Ardabili in 2022.
Methods: The experimental factors were included salinity levels (no salinity as control, salinity of 60 and 120 mM) by NaCl, application of Azosperlium (no inoculation as control and seed inoculation with Azosperlium), nanoparticles foliar application (foliar application with water as control, foliar spraying 0.8 g.L-1 nano zinc oxide, 50 mg.L-1 nanosilicon, combined foliar application nanozinc oxide as 0.4 g.L-1 and nano silicon as 25 g.L-1).Results:The application of azospirlium and nanoparticles in 120mM salinity increased proline content (37.46percent), hydrogen peroxide (41.66 percent), malondialdehyde (37.57percent) and the activity of peroxidase and polyphenol oxidase enzymes (53.86 and 47percent, respectively) in no of salinity and no application of azospirlium and nanoparticles. Application of azospirlium and nanoparticles increased the content of soluble sugar (18.68 percent) and catalase enzyme activity (28percent) in no application of azospirlium and no foliar spraying.No application of azospirlium and nanoparticles under 120 mM salinity increased dry matter remobilization from aerial organs (54.25percent) and the contribution of dry matter remobilization from aerial organs (126.14percent) in the application of azospirlium and nanoparticles under no salinity condition.
Conclusion:It seems that the application of Azosperlium and nanoparticle foliar application can increase grain yield of triticale under salinity stress due to improved biochemical traits.
