Assessment of phytotoxicity of Nb-containing nano-composites on the basis of saponites with the use of cress-salad (Lepidium sativum L.)

Abstract

The purpose. To study phytotoxicity of Nb-containing nano-composites on the basis of saponites on an instance of test-crop cress-salad (Lepidium sativum L.). Methods. Method of the scanned electronic microscopy, method of study of phytotoxicity on test-plants, statistical. Results. Safety is shown of use of Nbcontaining nano-composites, unlike to nano-particles Nb2O5 on an instance of test-culture Lepidium sativum L. Conclusions. Sparing action on germinative energy, germination and growth indexes of test- culture Lepidium sativum L. at use of nano-composites on the basis of saponite was not revealed. That testifies to safety of these nano-matters. Biotesting of Nb-containing nano-particles has shown inhibition of growth indexes of test-culture.
