Preparation and evaluation of Nano - micronutrients of zinc and iron slow release and its effect on germination and physiological indices of wheat bread (Triticum aestivum)

In recent years, research on the application of Nano science in various fields, including in the agricultural sector, has been considered. Considering the importance of evaluation and performance of nanoparticles in plant nutrition, in this study, the effect of iron and zinc nanoparticles on germination and seedling growth of native and modified wheat cultivars under laboratory conditions has been investigated. A factorial experiment was conducted in a completely randomized design with 5 replications at the Faculty of Life Sciences of Kharazmi University of Tehran. The investigated factors included different concentrations of iron nanoparticles (0.01 and 0.02 g/l), Nano-fertilizer (0.01 and 0.02 g/l) on two wheat cultivars including Bait (susceptible to Zinc and iron deficiency) and N-91-17 (modified with high iron and zinc absorption capacity). By applying iron and zinc treatment in experimental units, the basic characteristics of wheat growth including root length, stem, germination percentage, germination rate and seedling weight were evident. The results of germination test showed that Vigor index based on seedling length, seedling weight, stem fresh weights, root fresh weight and seedling length in iron Nano code and zinc compared to control in treatment of 0.20 g/l at probability level one The percentage is meaningful. In general, the results of the experiments showed that iron and zinc nanoparticles increase germination strength as well as more uniform seeding of wheat.
