“…The highest correlation coefficient was that between shoot fwt and total fwt (r = 0.998**, p < 0.01) for soybean var 35 and (r = 0.996**, p < 0.01) for soybean var 22. The findings in our study were consistent with previous studies in rice and common beans [76,77]. Moreover, these germination parameters exhibited a negative correlation with H 2 O 2 and MDA.…”

Background Considering titanium dioxide nanoparticles (TiO2 NPs) role in plant growth and especially in plant tolerance against abiotic stress, in the present work, TiO2 NPs were green synthesized using an aqueous solution of Aloe vera leaf extract as a capping agent and titanium tetrachloride as a precursor. These green synthesized TiO2 NPs were characterized using different techniques: UV spectrophotometer, scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). Results revealed that synthesized TiO2 NPs possess a tetragonal morphology with a size ranging from 10 to 25 nm. Additionally, the present work evaluated the effects of three concentrations of TiO2 NPs (0, 30 and 50 ppm) and six NaCl concentrations (0, 25, 50, 100, 150 and 200 mM) and their interactions with respect to germination parameters, vigor indices, oxidative stress and DPPH free radical scavenging of two varieties of soybean (Glycine max L. var. 22 and 35). Results Results demonstrated that all germination traits and vigor indices were negatively affected under all salinity levels. Also, the contents of hydrogen peroxide (H2O2) and malondialdehyde (MDA) were significantly increased by increasing the NaCl concentrations in two soybean varieties. Most interestingly, TiO2 NPs (30 ppm) mediated positive effects on germination parameters, reducing H2O2 and MDA contents by enhancing antioxidant (decreasing IC50) whereas 50 ppm showed an intermediate response under both control and saline soil conditions. Conclusion Our findings demonstrate the growth enhancement effects of TiO2 NPs application as well as its ameliorative potential in dealing with salinity.

“…Similarly, it was reported that the emergence and growth of castor bean were more affected by the salinity level than by the cationic composition of the irrigation water 21 . Also, it was stated that shoot height values of common bean genotypes were affected by salinity (NaCl) only at 200 mM 13 whereas shoot height of pinto bean 22 and emergence rate, shoot height and leaf area of castor bean 23 were reduced by increased salinity (NaCl) level. The latter researchers also concluded that the reduction in emergence, plant height, leaf area and chlorophyll a and b was much greater for an increase in salinity from 50 to 100 mM NaCl than that from 0 to 50 mM NaCl.…”

“…In addition, in many studies on salt tolerance, it is not been possible to determine the detrimental effects on growth that is associated with whether the level of salinity or the kind of salt present in the water or soil solution. Therefore, the exploitation of seed performance under salt and salinity effect on emergence and early seedling growth stage will be helpful for improving the choice of genotype suited to perform best under known conditions of salinity 13 .…”

Suitability of poor quality water for irrigation depends on salinity level and solute concentration in the water and selected crop. Salt stress is a major potential constraint for faba bean. The present study aimed to investigate the effects of different Cl- and SO4-containing salt sources in irrigation water with different salinity levels on emergence, early seedling growth and photosynthetic capacity of six faba bean genotypes. The negative effect order of salinity level was high (3 dS/m) > medium (2 dS/m) > low (1 dS/m) > control (0.05 dS/m) for all investigated parameters except dry root weight. The negative effects of Cl-containing salt sources were higher than that of SO4-containing salt sources. The worst and the best performing genotypes were determined as III-28 and III-29 on emergence percentage at 10th DAS, I-29 and III-1 on mean emergence time, III-22 and III-1 on shoot height, III-1 and I-29 on fresh biomass weight, III-22 and III-28 on fresh shoot weight, III-29 and I-29 on fresh root weight, respectively. This study showed that faba bean genotypes have different behaviors in terms of response to the increasing salinity levels artificially makeup by using different salt sources indicating that salt response of faba bean is genotype-specific.

“…The mean yield of maize in Cameroon is ~2.1 t/ha, a level which represents only 19% of what is attained by some producers in developed countries [ 3 ]. The crop’s relatively poor performance in the Cameroon, at least in part, is due to the fact that salinity affects about 671 thousand hectare of arable land [ 4 ], while some 85% of the soil is acidic and therefore P deficient [ 5 ]. While breeding for adaptation to either saline and/or P deficient soils has the potential to raise yield potential [ 6 ], the yield can also be enhanced by exploiting the ability of plant growth-promoting rhizobacteria (PGPR) to solubilize phosphate in the soil and to mitigate salinity stress [ 7 ].…”

The Response of Maize to Inoculation with Arthrobacter sp. and Bacillus sp. in Phosphorus-Deficient, Salinity-Affected Soil

et al. 2020

Salinity and phosphorus (P) deficiency are among the most serious soil factors constraining crop productivity. A proposed strategy for alleviating these stresses is supporting plants by inoculation with growth-promoting rhizobacteria (PGPR). Here, a comparison of the ability of two maize composite and two F1 hybrid varieties to tolerate a P deficiency in either a saline or a non-saline environment showed that the uptake of nutrients by all four entries was significantly reduced by the imposition of both soil salinity and P deficiency, and that their growth was compromised to a similar extent. Subsequently, the ameliorative effect of inoculation with three strains of either Arthrobacter sp. or Bacillus sp. in an environment, which suffered simultaneously from salinity and P deficiency, was investigated. Inoculation with each of the strains was found to limit the plants’ uptake of sodium cations, to increase their uptake of potassium cations, and to enhance their growth. The extent of the growth stimulation was more pronounced for the composite varieties than for the F1 hybrid ones, although the amount of biomass accumulated by the latter, whether the plants had been inoculated or not, was greater than that of the former varieties. When the bacterial strains were cultured in vitro, each of them was shown as able to produce the phytohormones auxin, abscisic acid, gibberellins, and cytokinins. The implication is that since the presence in the rhizospere of both Arthrobacter sp. and Bacillus sp. strains can support the growth of maize in salinity-affected and P deficient soils in a genotype-dependent fashion, it is important to not only optimize the PGPR strain used for inoculation, but also to select maize varieties which can benefit most strongly from an association with these bacteria.
