The effect of biopriming (Trichoderma fungus) and seed coating with nano-chelate on the activity of antioxidant enzymes of two varieties of quinoa (Chenopodium quinoa willd.) abstract

Quinoa (Chenopodium quinoa Willd.) is an annual herb native to the Andes mountains in Bolivia, Chile, and Peru. It is very digestible and a rich source of protein, iron, phosphorus, various vitamins, and omega-3. Biopriming is a biological pretreatment of seeds that is subject to a combination of soaking and seed inoculation with beneficial organisms for seed protection, a technique that helps seed germination in different conditions. It is used to improve seed performance. These compounds protect the seeds from the stresses that are likely to occur in the environment. To investigate the effect of biopriming (Trichoderma fungus) and seed coating with nano-chelate on the length and dry weight of seedlings of two quinoa cultivars, an experiment was conducted in the form of a completely randomized basic design in four replications in the Laboratory of Seed Science and Technology of Mohaghegh Ardabili University in 2024. The experimental treatments included pre-treatment at three levels (control, biopriming, and seed coating) and quinoa cultivars (TT Kaka and Giza). The results showed that the highest seedling length and dry weight were observed in the seeds inoculated with Trichoderma fungus in the Giza variety. The Giza variety was 26.12% longer than the Ti Ni Kaka variety. Also, the dry weight of the Giza variety was 43.15% higher than the TT Kaka variety. Also, Trichoderma fungus increased seedling length by 36.58% and dry weight by 46.25% compared to the control treatment. According to the results of this research, it can be concluded that biopriming with Trichoderma fungus in Giza cultivar improves the germination characteristics and growth of seedlings by increasing the vigor of seeds and seedlings.
