Effectiveness of carrot (Daucus carota L.) seed priming using nanocomposites of metallopolymers in non-aqueous solvents

Obtaining a levelled quality product depends primarily on the quality of the seed. There are a large number of treatments that improve the sowing quality of seeds. However, seed priming has the greatest influence on the friendship and germination rate. Seed priming is a process of activation of plant defence system after exposure to stressful environmental events, which leads to increased viability of plants to combat stress and is of great interest to study. This exposure leads to changes in seed metabolism and subsequently supports the successful establishment of plants in the environment through faster and more significant seed germination and growth of developing seedlings. The remarkable increase in the application of nanotechnology in agriculture has also stimulated research on plant nanoprime. Nanoparticles have been found to be more effective in influencing growth, quality, yield, reactive oxygen species and homeostasis in plant seeds than other priming methods. However, there is a need to test nanoparticles showing toxic effects on seed germination and seedling growth in deliberate seed treatment to understand the possible effects on plants and human health. Treatment with silver nanoparticles had a positive effect on improving the sowing quality of Marlinka carrot seeds. Application of silver nanocomposites in pre-sowing treatment with 0.25% ethylene glycol solution with colloidal silver solution 100 ppm/l promoted germination rate increase from 89% in the control to 96% in the variant. Increase in germination rate from 16.5 on the control to 18.6 on the variant of pre-sowing preparation.
Keywords: Priming, nanocomposites of metallopolymers, nanocleaners, ethylene glycol, germination, seedbed preparation.
