“…This effect was more pronounced in axillary spikes, where P. extremaustralis IB-К13-1А inoculation approximately doubled grain weight and number, with lesser effects following A. kashmirensis IB-К1 inoculation. These positive effects of bacterization on wheat productivity occurred following insufficient summer rainfall at the time of grain filling, in agreement with reports of bacterial preparations having greater effects on growth and yield of droughted plants (Kuzmina and Melentev, 2003; Rubin et al, 2017). The cost of seed bacterization per hectare [2400 roubles (about $37) with a sowing density of 3–4 million seeds ha −1 ] was overshadowed by the economic gain of enhanced wheat yield due to PGPR action [22,000 roubles (more than $300) per hectare], suggesting such treatments may be commercially appealing to farmers.…”

Phytohormone Mediation of Interactions Between Plants and Non-Symbiotic Growth Promoting Bacteria Under Edaphic Stresses

The capacity of rhizoshere bacteria to influence plant hormonal status, by bacterial production or metabolism of hormones, is considered an important mechanism by which they promote plant growth, and productivity. Nevertheless, inoculating these bacteria into the plant rhizosphere may produce beneficial or detrimental results depending on bacterial effects on hormone composition and quantity in planta, and the environmental conditions under which the plants are growing. This review considers some effects of bacterial hormone production or metabolism on root growth and development and shoot physiological processes. We analyze how these changes in root and shoot growth and function help plants adapt to their growth conditions, especially as these change from optimal to stressful. Consistent effects are addressed, along with plant responses to specific environmental stresses: drought, salinity, and soil contamination (with petroleum in particular).
