Varavkin V. Regulation of physiological processes in sugar beets and cereal grains using membrano-active compounds.

It has found that plant grows regulators (GR) Etamon, Triman 1, humat of potassium and, Dimex and Hart particular, at low concentrations increase significantly the permeability of cell membranes. It has been shown that physiological activity of GR (by their action on cell membranes) in accorance with their action on the whole plants. Weat seed treatment by these GR increased seedlings resistance to short-term action of extremal temperatures. It has been established that GR Etamon and Hart treatment of sugar beet seeds or plants, increases photosynthetic rate due to both decreases of leaf resistance, respiratori rate and increase in chlorophyll content, and in the raise ratio of phytogormons (IAA+cytokinins)/ABA. Under field conditions the productivity of sugar beet (treated by GR Etamon, Dimex and Hart) and spring barley (treatid by humat of potassium) increased significantli.
