Влияние наночастиц на физиологические характеристики и активность ферментов растений, выращенных в соленых почвах

Abstract

Lately, use of nanoparticles in ecological problems solution of agriculture rouses a great interest. One of the interesting directions in nanotechnologies is nanoparticles application in agricultural plants salt-tolerance. Normal development of the plan provision in the saline soils was tried using from nanoparticles on the basis of Al2O3, CuO, Fe2O4, ZnO, TiO2 metals. For this purpose, an influence of nanoparticles on seeds hydration, soil rhizosphere, contamination and planes shooting in the normal and saline soils was investigated. In this connection before sowing the seeds were worked out by the nanoparticle dust. An impact of nanoparticles on plants shooting energy. Growth and development, photosynthetic pigments quantity. Photosystem activity and plant ferments concern future duties. The nanoparticles diffusion in seed endosperm was studied on the basis of the EPR method in the researches. Therefore, the samples were prepared from different layers of the seeds endosperm to determine EPR signal, the plant seeds were exposed to the influence of nanoparticles in dispersible solution for one day. Influence of nanoparticles on chlorophyll quantity in shooting leaves of the grown cultures in the normal and saline soils using of the spectroscopic method was determined. It was determined as a result of the experiment that nanoparticles stimulate shoots development changing a hydration character of the seeds, diffusing to the seeds, creating an opportunity for shooting in the saline soils.
