INFLUENCE OF KORNEVIN AND RHIZOTORFIN ON THE HORMONAL STATUS AND EFFECTIVENESS OF THE BEAN SYMBIOTIC SYSTEM
2020
Volobueva, O.G.
In condition of field experiment with a bean (Phaseolus vulgaris L.) cultivar Heliada and Shokoladnitsa was studied the effect of seed treatment with the biopreparation based on root nodule bacteria Rhizotorfin and growth regulator Kornevin on the content and ratio of phytohormones in leaves, stems and roots with nodules during the budding-beginning of flowering phase (the period of the most active nitrogen-fixing activity in beans) and the symbiosis efficiency. Interrelation between indicators and indicators of ultrastructure of tubers and nitrogen-fixing activity of leguminous plants are established. It was established that the most responsive to the treatment of Kornevin was the Heliada variety. The treatment of Heliada seeds led to an increase in the area of bacteroids and a decrease in the area and number of inclusions of poly-ß- hydroxybutyric acid (PHB), against the background of an increase in auxins in leaves and stems, cytokinins in leaves and roots with nodules, gibberellins in stems and roots with nodules and lower ABA in stems and roots with nodules. The most responsive to the treatment of Rizotorfin was the variety Shokoladnitsa. The treatment of Shokoladnitsa seeds with Rhizotorfin led to an increase in nitrogen-fixing activity in nodules against the background of an increase in the area and number of bacteroids, volutin inclusions, with a minimum number of PHB inclusions, against the background of an increase in cytokinins in all vegetative organs of plants.
