The interrelation of spring wheat productivity with the content of pigments under the influence of nanosilicon

The structure of spring wheat Daria, the content of chlorophylls A and B and carotenoids are investigated in the article. The leaf index in wheat under the influence of Nanosilicon increases compared with the control by 28% and compared with Vincite - by 14%. A significant increase in the content of pigments involved in photosynthesis was established under the influence of the drug. So, if in the phase of 4 leaves of chlorophyll in the variant with the preparation it was 10% more, then in the phase of the beginning of flowering in the experimental version it was 70% more, which indicates the prolongation of the green leaf life and the preservation of assimilation activity. The treatment of wheat seeds with Nanosilicon solution before sowing contributes to an increase in the capacity of the photosynthetic apparatus during the growing season in the experimental version, to a greater extent than in the variant with Vincite and control. Under the influence of Nanosilicon, the accumulation of sugars lasts a week longer than that of the control variants, and their content is twice as large, which indicates that assimilates accumulate in the experimental version for a longer time than in the control. It was established that the yield of wheat Daria under the influence of treatment with Vincite increased by 8% compared with the control without treatment, and under the influence of Nanosilicon its growth amounted to 16.6% compared to untreated one. The increase in wheat yield under the influence of Nanosilicon was due to an increase in both the number of grains in the head and due to their mass. Under the influence of processing, an increase in the size of heads of wheat by 1.5-2 times occurs both in comparison with the control group and in comparison with the treated Vincite.
