EFFECT OF BIOPRODUCTS RHIZOTORPHIN AND ALBIT ON THE CONTENT OF PHYTOHORMONES IN DIFFERENT VARIETIES OF PEA PLANTS AND EFFICIENCY OF SYMBIOSIS
2019
Volobueva, O.G.
In the conditions of microplot trial with pea plants varieties Nord and Multik studied the effect of seed treatment of these plants with Risotorphine and Albit biopreparations on growth rates, content and ratio of endogenous phytohormones in leaves, stems and roots with nodules in the budding-beginning of flowering phase (the period of the most active nitrogen-fixing activity in peas) and effectiveness of symbiosis. It was found that the most responsive to the processing of Rizotorfin was the variety Nord. Seed treatment of plants of this variety led to an increase in the height and above-ground mass of plants, the mass of roots with nodules, the amount and mass of nodules. This occurred against the background of an increase in auxins, zeatin in the roots with nodules, gibberellins in the stems. The most responsive to the treatment of Albit was the variety Multik. The treatment of seeds of this variety with Albit led to an increase in the height and above-ground mass of plants, the mass of roots with nodules, the number and mass of nodules against the background of an increase in auxins in leaves, stems and roots with nodules, zeatin in stems, gibberellins in leaves, abscisic acid in leaves, stems and roots with nodules. Growth rates correlated with those of the nitrogen-fixing activity of these plants.
