The effect of seed treatment with various materials of chitosan and hydroxycinnamic acids on the growth of barley seedlings was evaluated. It was shown that chitosan-hydroxycinnamic acid conjugates and nanoparticles had no negative effect on the initial stages of the growth of barley seedlings. Adaptation of seedlings after 24 h exposure to 4 % NaCl in the samples of conjugates of 30 kDa chitosan with caffeic and ferulic acids was more effective. There was a decrease in proline contents and restoration of the growth activity under post-stress conditions.

It was established that the treatment of clover seeds with radio frequency (RF) electromagnetic field and low pressure (200 Pa) RF plasma excited at a frequency of 5.28 MHz has a stimulating effect both on the germination of seeds and on the growth and development of plants grown in laboratory and field conditions. Plasma treatment for 5 min led to the greatest stimulation of seed germination and germination energy, a significant increase in the biomass of shoots and roots. At the same time, the content of phenolic compounds and flavonoids in plant leaves decreased.
