“…The studies conducted at Arkansas University of Nanotechnology Center at Little Rock, also at Tambov State University named after G.R. Derzhavin (Training Innovation Center for Nanotechnologies and Nanomaterials) together with the Tambov State Technical University (Co Ltd "NanoTehTsentr") and others, have shown that putting tomato seeds, tobacco, sainfoin, rape, wheat and some other crops into a nutrient solution containing carbon nanotubes leads to stimulation of their germination, plant growth and development improvement, biomass accumulation increase and also to higher yields due to the penetration of nanotubes through the seed coats into various plant organs [12][13][14][15][16][17][18][19]. We have also managed to identify the effects, observed during our experiments, where we used for pre-sowing seed treatment new nanoporous (nano) chips based on carbonaceous sorbents with the different plant protection products of biogenic nature included into their composition.…”

The present level of development of agricultural science has led to the emergence of a new method of plant protection, it is based on improving the immune potential of plants using elicitors, but not on the destruction of pathogens using pesticides. We have studied the effect of disease resistance inducers based on chitosan, organic acids and other substances with elicitor activity, being part of (nano) chips of different composition (matrix carrier -modified natural minerals, activated carbons, nanotubes, graphene, etc..) for pre-sowing seed treatment and for foliar fertilizing. We have studied their influence on growth, development, the incidence of rape plants, the quantity and quality of their crop. We have also determined the efficiency of (nano) chips depending upon their nature and carrier matrix composition.Keywords: elicitors; (nano) chips; pre-sowing seed treatment; growth; development; the incidence of rape plants; the quantity and quality of their crop

Since their discovery, carbon nanotubes have been prominent members of the nanomaterial family. Owing to their extraordinary physical, chemical, and mechanical properties, carbon nanotubes have been proven to be a useful tool in the field of plant science. They were frequently perceived to bring about valuable biotechnological and agricultural applications that still remain beyond experimental realization. An increasing number of studies have demonstrated the ability of carbon nanotubes to traverse different plant cell barriers. These studies, also, assessed the toxicity and environmental impacts of these nanomaterials. The knowledge provided by these studies is of practical and fundamental importance for diverse applications including intracellular labeling and imaging, genetic transformation, and for enhancing our knowledge of plant cell biology. Although different types of nanoparticles have been found to activate physiological processes in plants, carbon nanotubes received particular interest. Following addition to germination medium, carbon nanotubes enhanced root growth and elongation of some plants such as onion, cucumber and rye-grass. They, also, modulated the expression of some genes that are essential for cell division and plant development. In addition, multi-walled carbon nanotubes were evidenced to penetrate thick seed coats, stimulate germination, and to enhance growth of young tomato seedlings. Multi-walled carbon nanotubes can penetrate deeply into the root system and further distribute into the leaves and the fruits. In recent studies, carbon nanotubes were reported to be chemically entrapped into the structure of plant tracheary

“…The most significant features of nanotubes in terms of biology and medicine are high sorption capacity, low toxicity and ability to infiltrate cell membranes [2][3][4][5][6][7][8][9]. The test-studies (on tseriodafniyah, protococcal green algae, GMO culture of luminescent bacteria E.coli M-17 (test system (Ekolyum"), house mice) revealed that the carbon nanotubes refer to III-IY hazard class on ecotoxicological five-point scale.…”

The tests have also indicated the ability of multi-walled carbon nanotubes to penetrate the roots and reach the leaves of plants as well, going up the conduction system and leaving cells undamaged (test object -sainfoin) [4][5][6]. Growth and seedling development stimulation along with an increased peroxidase activity were also confirmed (nanomaterial concentration -100 to 1000 mg / l).…”

Abstract. This particular study deals with the impact of pre-sowing nanotube-based seed treatment technology on rapeseed (Brassica napus) growth and yield. During field tests we identified a significant yield increase as a result of applying the pre-sowing nanotube-based seed treatment technology. The main treatment agents were physiologically active nanochips consisting of carrier matrix nanotubes with eliciting activity ("Taunit", "Taunit-M", "Taunit-MD", and graphene). Enriching nanochips with insecticide-fungicide Kruizer-rape for guaranteed seed protection from crucifer flea allowed to raise the yield up to 8.08 t / ha -12.28 t / ha.
