“…Previous studies showed that water shortages decrease the photosynthetic rate, stomatal conductance and intercellular CO 2 content 5 , 6 . Moreover, research also showed that water stress at each stage could reduce the grain weight per plant, number of effective ears, number of spikelet and 1000 grains weight, which resulted in the shrinkage of grain, and a decrease in yield 7 .…”

Revealing the effects of drought stress on the photosynthetic characteristics and yield of naked oats (Avena nuda L.) is significant for enhancing the productivity of oats. In this study, a potted experiment consisting of four water levels was conducted in the Bashang area of Hebei Province, China. The drought stress period was established as the continual 8 days during the jointing-heading stage. The aims were to reveal the impacts of drought stress on the photosynthetic characteristics and yield of naked oats during the critical stage. The results showed that the photosynthetic rate (Pn), transpiration rate (Tr), and stomatal conductance (Gs) decreased under all conditions of drought stress. The intercellular CO2 concentration (Ci) decreased under light drought stress, while it increased under moderate and severe drought stress. The initial chlorophyll fluorescence rate (Fo) increased by 9.03–50.92% under drought stress, and the maximum fluorescence rate (Fm) decreased by 8.49–19.73% under drought stress. The photochemical efficiency (Fv/Fm) increased by 10.37–24.12% under drought stress. The yields decreased by 9.5–12.7%, 16.8–27.0% and 44.1–47.7% under light, moderate and severe drought stress during the critical stage, respectively. The grains per panicle decreased by 1.7–12.5%, 8.3–24.3% and 32.7–34.2% under light, moderate and severe drought stress conditions, respectively. The 1000-grain weight decreased by 5.7–8.6%, 12.7–14.5% and 16.8–19.1% under light, moderate and severe drought stress conditions, respectively. The panicle numbers did not vary significantly among the different drought stress treatments. The photosynthetic rate, stomatal conductance and transpiration all had significant positive relationships with the yield of naked oat (P < 0.01). Parameters of PS II except for Fo all had significant positive relationships with the yield of naked oats (P < 0.05). This study is significant for enhancing the production efficiency of naked oat under drought stress.

“…Recently, the use of biostimulants has been of particular interest. According to the FAO, the term "biostimulant" is defined as "a product that activates the processes of photosynthesis, growth, metabolism in order to stimulate one or more factors: efficiency the efficiency of nutrient uptake by plants; plant resistance to abiotic stresses; the predominance of qualitative characteristics of crops " [1][2][3][4][5][6][7][8][9][10].…”

“…[4] Biostimulants based on microorganisms often have fungicidal properties, that is, they suppress the development of pathogenic microflora [5]. The positive effect of biostimulants can be seen in an increase in the content of photosynthetic pigments and an increase in resistance to stress factors, in particular, to drought [6].…”

The article presents the results of a study of biostimulants Fitosporin-M, Zh (AS) + amino acids and Bionex-Kemi, Zh, (NPK 21:4:4) + ME on potato productivity indicators. As a result of1 the research, a positive effect of biostimulants on the growth and accumulation of underground biomass of Solanum tuberosum L. variety "Zakhar" was established. The analysis showed that when Solanum tuberosum L. plants of Zakhar variety are treated with Bionex-Kemi, Zh, NPK 21:4:4 + ME, the content of starch in tubers increases by 1.3 %, and when plants are treated with Fitosporin-(M, F (AS) + amino acids) - by 0.9 % in comparison with the control variant. The accumulation of underground potato biomass was more intense when using Bionex-Kemi, G, (NPK 21:4:4) + ME. For the cultivation of potatoes in the conditions of the Orenburg Cis-Urals, it is recommended to use the biostimulator Bionex-Kemi, Zh, (NPK 21:4:4) + ME (bioactivated nitrogen-phosphorus-potassium fertilizer), which stimulates plant growth and the accumulation of underground biomass.

“…The strawberry is an economically important berry species [ 37 ] that is characterized by high sensitivity to water deficiency [ 38 , 39 , 40 ]. This species is therefore a very good object of research on the effects of factors that can potentially relieve drought stress, including the effectiveness of inoculating plants with plant growth-promoting bacteria.…”

Due to the observed climate warming, water deficiency in soil is currently one of the most important stressors limiting the size and quality of plant crops. Drought stress causes a number of morphological, physiological, and biochemical changes in plants, limiting their growth, development, and yield. Innovative methods of inducing resistance and protecting plants against stressors include the inoculation of crops with beneficial microorganisms isolated from the rhizosphere of the plant species to which they are to be applied. The aim of the present study was to evaluate 12 different strains of rhizosphere bacteria of the genera Pantoea, Bacillus, Azotobacter, and Pseudomonas by using them to inoculate strawberry plants and assessing their impact on mitigating the negative effects of drought stress. Bacterial populations were assessed by estimates of their size based on bacterial counts in the growth substrate and with bioassays for plant growth-promoting traits. The physiological condition of strawberry plants was determined based on the parameters of chlorophyll fluorescence. The usefulness of the test methods used to assess the influence of plant inoculation with rhizosphere bacteria on the response of plants growing under water deficit was also evaluated. A two-factor experiment was performed in a complete randomization design. The first experimental factor was the inoculation of plant roots with rhizosphere bacteria. The second experimental factor was the different moisture content of the growth substrate. The water potential was maintained at −10 to −15 kPa under control conditions, and at −40 to −45 kPa under the conditions of water deficit in the substrate. The tests on strawberry plants showed that the highest sensitivity to water deficiency, and thus the greatest usefulness for characterizing water stress, was demonstrated by the following indices of chlorophyll “a” fluorescence: FM, FV, FV/FM, PI, and Area. Based on the assessment of the condition of the photosynthetic apparatus and the analysis of chlorophyll “a” fluorescence indices, including hierarchical cluster analysis, the following strains of rhizosphere bacteria were found to have favorable effects on strawberry plants under water deficit: the Bacillus sp. strains DLGB2 and DKB26 and the Pantoea sp. strains DKB63, DKB70, DKB68, DKB64, and DKB65. In the tests, these strains of Bacillus sp. exhibited a common trait—the ability to produce siderophores, while those of Pantoea sp. were notable for phosphate mobilization and ACCD activity.
