In order to study the effects of seed inoculation by cycocel and biofertilizers on yield, antioxidant enzymes activity and some biochemical traits of wheat (Triticum aestivum L.) under soil salinity condition, a factorial experiment was conducted based on randomized complete block design with three replications in a research greenhouse of Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardabili in 2016. Treatments were included salinity in four levels [no salt (as control), salinity 25, 50 and 75 mM by NaCl and seed inoculation by biofertilizers and cycocel in six levels [no inoculation with cycocel and bio fertilizers as control, inoculation by Pseudomonas, Azosprilium, both inoculation Azosprilium and Pseudomonas, inoculation by cycocel in concentration 10-5 and 10-6 mM]. The results showed that 75 mM salinity increased protein content and antioxidant enzymes activity such as catalase, peroxidase and polyphenol oxidase (43.39, 103.9, 97.83 and 143 % respectively) in comparison with no salinity. The lowest electrical conductivity (65.8 µs.cm-1) and the highest relative water content in flowering stage (87.86 %), protein content (17.7%) and grain yield (2.83 g per plant) were obtained in no salt and both inoculation Azosprilium and Pseudomonas. The highest electrical conductivity (111.83 µs.cm-1) and the lowest relative water content in grain filling period (49.6 %), protein content (10.57 %) and grain yield (0.98 g per plant) were obtained in the highest salinity level and no inoculation with cycocel and bio fertilizers.
