Volobueva, O.G.
The ultrastructure of nodules of bean plants of the Heliada and Shokoladnitsa varieties, the seeds of which were treated with Rizotorfin, Albit, Kornevin, and Epin-Extra, and soybean plants of the Mageva and Svapa varieties, the seeds of which were treated with Rizotorfin and Epin-Extra, were studied. An increase in the activity of nitrogenase in bean plants of the Heliada variety and soybean variety Svapa was established when treated with Epin-Extra against the background of an increase in the area of bacteroids, the area and amount of volutin and a decrease in the area and number of inclusions of poly-ß-hydroxybutyric acid (PHB). In the bean variety Shokoladnitsa and soybean variety Mageva, the protective effect of Rizotorfin was manifested, under the influence of which an increase in the activity of nitrogenase in nodules and an increase in the area and number of bacteroids, inclusions of volutin, with a minimum content of PHB, were observed. The presence of bacteroids, volutin and PHB inclusions in symbiosomes is considered as a new additional indicator of the activity of the symbiotic system.
