The influence of spring barley extracts on pseudomonas putida PCL1760

Abstract

The aim of the present study was to evaluate the influence of different extracts (water, ethanol, enzymatic) from germinated seeds of spring barley on the development of Pseudomonas putida bacteria. The tests on optical density were performed to study the influence of different extracts on the development of model extracts. The analysis of the influence of different extracts from germinated seeds of spring barley on biological agent - Pseudomonas putida PCL1760, contained in biopreparations for crop protection showed that ethanol extract from Raushan variety of spring barley increased the resistance of Pseudomonas putida PCL1760 to the heat and osmotic stresses. All the types of extracts did not contribute to the increase of bacteria resistance to low temperatures. There was no significant difference established between the activity of spring barley extracts with vernalization and without vernalization. The materials of the study showed that ethanol extracts from spring barley can be used for the development of Pseudomonas spp. based on biopreparations for the enhancement of biocontrol microorganisms (BCMs) activity.

The Productivity of Spring Wheat Depending on the Depth of Seeding in the Predkamye of the Republic of Tatarstan

“…The seeding depth for spring wheat is of significant practical importance. It depends on the soil, moisture content, sowing time and seed quality [4][5][6].…”

Assessment of the Influence of Meteorological Factors and Agricultural Background on the Productivity of Spring Wheat Ulyanovskaya 105 in the Predkamye of the Republic of Tatarstan

“…An increase in the number of varieties is a condition for expanding the sown areas of spring wheat in the Middle Volga region [2,3,8].…”

Fertilizers and biological products used for cultivation of perennial grasses on gray forest soils of the Middle Volga region

“…Therefore, much attention is paid to the use of scientific and technological achievements, including fertilizerstimulating compounds, biological preparations, and chelated micronutrient fertilizers. According to foreign [1][2][3] and Russian [4][5][6] scientists, they improve the stress resistance of plants, accelerate the accumulation of biomass, improve quality of the products, and contribute to a better wintering of winter rye and winter wheat due to internal reserves of cultivated crops. However, the use of biologically active substances is understudied, especially taking into account soil and climatic conditions of the forest-steppe zone of the Middle Volga region, which became the basis for the selection of the object and the direction of our research.…”
