Growth-promoting potential of Herbaspirillum rhizosphaerae bacteria on wheat seedlings (Triticum aestivum L.)

The development of sustainable agriculture requires reducing the chemical load on agroecosystems. One of the ecological approaches is the use of biopreparations based on rhizobacteria that stimulate plant growth. Inoculation of early wheat (Triticum aestivum L.) sprouts with Herbaspirillum rhizosphaerae UMS-37[T] bacteria resulted in an increase in the length of roots and shoots, and also affected the content of proline, malondialdehyde, nitric oxide and catalase activity in sprouts, which indicates the induction of systemic plant resistance mechanisms. The strain H. rhizosphaerae UMS-37[T] demonstrated pronounced antifungal activity against field strains of mycelial fungi of the genus Fusarium. The results of this work can be used in the development of environmentally friendly and competitive biopreparations in adaptive agriculture that are capable of activating plant defense systems and controlling fusarium of the most important agricultural crops.
