Abstract:

Micronutrients are part of enzymes and play an important role in plant germination. Purpose of our study was to establish the effect of pre-seed treatment of chufa tubers with metal nanoparticles on the growth of the root system and seedlings in the early stages of development. Laboratory tests were performed on seed of tiger nut cultivar Pharaoh. Experiment involved two methods of treatment: pre-sowing treatment of seeds with nano-particles solutions of manganese, zinc, copper and iron with a concentration of 60 ppm and re-application of these solutions after seedling emergence. The weight of seedlings and roots was determined at 3rd and 10th days after emergence in treated and untreated variants. Pre-sowing treatment of chufa tubers with all forms of micronutrients significantly increased the weight of the plant (excluding the weight of seeds), and the most effective were treatments with copper and iron. Treatment with copper colloidal solution increases in root weight at 3rd day on 156% compared to control without treatment and this dynamic stayed at 10th day. Most affective treatment is iron colloidal solution. This treatment gives +99% of root weight at 3rd day and 194% at 10th day after germination compared to control in same time. Colloidal forms of manganese, copper and iron also significantly increased the weight of the shoot. Increase in the mass of roots, shoots and plants is observed in plants with foliar fertilizing, but a few variants have an insignificant difference or inhibit the assimilation processes of plants. Pre-sowing treatment with zinc citrate at 60 ppm decreased root and shoot weight in chufa.
