Pectin was extracted from leaves of hydrobiont of Zostera marina from the Black Sea coast of the Odessa region. Test cultures of corn and wheat were used as the objects of the study of biological activity effect of zosteran-boron supramolecular complexes on the growth function of the root and the ground part. The mass of the root system and the ground part of the plant was measured according to original methodology in 96 hours after the experiment was started (seed soaking in distilled water for 24 h and in the solution of the supramolecular complex zosteran–boric acid for 72 h). As a result of seed germination on the solutions of supramolecular complexes of different composition, it was found out that complexes have a significant activating effect on the growth processes of aboveground part of plants. It was demonstrated that the biological activity of solutions substantially depends on the nature of culture. Corn showed a higher overall biological activity of supramolecular complexes compared with wheat. Solution of the supramolecular complex of zosteran–boric acid in a 1:1 molar ratio was found to be effective for both cultures. Zosteran–boric acid complexes in the molar ratio of 2:1 did not demonstrate high biological activity. High biological activity (107.87% for corn and 60.35% for wheat) was demonstrated by complex with zosteran–boric acid mass ratio of 1:20, and the formation of zosteran–boric acid complexes with molar ratio of 1:1 is the most probable case. It is caused by smaller sizes and better bioavailability of such complexes. Complexes with pectin-boric acid 2:1 molar ratio demonstrated lower biological activity (103.33% for corn and 11.18% for wheat). It can be explained by steric restrictions during penetration into the plant.  Product Description popup.authors Mokhniev Denys S Prymachenko Serhii V popup.nrat_date 2021-03-17 Close
