Effect of storage duration on some germination and vigor indicators of three Wheat cultivars seed in the north of Khuzestan province weather conditions

In order to study of the effect of storage duration on some germination and vigor indicators of three wheat cultivars seed in the north of Khuzestan province weather conditions an experiment was conducted at Agriculture and Natural Resources Research and Education center of Safiabad - Dezful in 2021. Experiment was conducted as factorial based on completely randomized design by four replications. Experiment factors include: four storage durations, 30, 60, 90 and 120 days and three wheat cultivars, Chamran2, Mehregan and Shabrang. Studied traits include: 1000 seed weight, seed germination rete, mean time and energy, normal seedling percent, seed allometric coefficient and vigor index. Results showed cultivar and storage duration interaction affected all studied traits. Shabrang cultivar seeds stored during 30 days had the most 1000 seed weight and the same cultivars seed stored during 120 days had the lowest normal seedling percent. Mehregan cultivars seed stored during 30 days had the most seed germination rete and energy, normal seedling percent, seed allometric coefficient and vigor index and the lowest mean germination time. Based on seed germination and vigor indicators evaluated by this research, studied wheat cultivars seeds were different for storability and in comparison of other studiec cultivars, Mehregan cultivar seeds had better storability behavior at North of Khuzestan province weather conditions.
