“…Glyphosate caused typical adverse alterations in the growth of wheat (Figure 1) expressed by obvious retardation of fresh biomass accumulation, and plant organs elongation, which is in accordance with earlier studies on different glyphosate-treated crops [4,9,12,14,28,43]. Glyphosate-suppressed plant growth is also a consequence of accumulation of ROS, which harm cellular biomembranes as is evidenced by the increased amount of MDA (Figure 2B).…”

“…Glyphosate is a non-selective herbicide and it affects not only weeds but crop plants as well. A number of articles documented that it substantially altered germination and physiological responses of different crops such as pea [4,[6][7][8][9], faba bean and common bean [10], soybean [11], tomato [12,13], maize [14,15], sorghum [10], wheat [6,7], etc. That is why the modulation of the herbicide action by application of ecologically safe plant growth regulators, which are capable to reduce the negative effects of the herbicide on non-target plants, gives rise to interest of fundamental and applied outlook.…”

Glyphosate is an extensively used herbicide because of its non-selective action for weed control. Salicylic acid (SA) is a phenolic compound that has the potential to increase plant tolerance to diverse stresses. To test SA ability to modulate plant responses to glyphosate we used young wheat (Triticum aestivum L.) seedlings grown as a water culture. Plants were sprayed with 1 mM SA, and 24 h later with 0.5 mM glyphosate. All measurements were performed 14 days after herbicide treatment. Wheat growth was reduced by glyphosate. Stress markers (proline and malondialdehyde) were significantly increased by glyphosate showing oxidative damages. Incapacity of wheat to cope with the oxidative stress was evidenced by reduction in thiols and phenolics content, accompanied by slight induction of superoxide dismutase and catalase activities. Enhanced activities of peroxidase, glutathione reductase and glutathione-S-transferase were expected to participate in glyphosate detoxification. SA applied alone had no important effects on measured parameters. SA pretreatment decreased stress markers and caused additional amplification of antioxidant defense systems in glyphosate-treated plants. Growth was partially restored in combine-treated plants due to SA application. SA probably triggered antioxidant defense to cope with the herbicide stress.

“…In the case of radicles, unlike the hypocotyl, all genotypes were similarly affected, both in the treatment of 0.06% and 0.12%, reinforcing the hypothesis that glyphosate affects radicle development more than the hypocotyl, also seen in soybean by Tillmann and West (2004) and Heinz et al (2011), and in pea by Mondal et al (2017).…”

Germination and initial seedling development are physiological processes that determine the establishment of crops. During heterotrophic growth, each seedling develops from the biomass of its seeds. Thus, verifying the potential of genotypes to mobilize reserves under stress has been important. The aim of this study was to investigate how glyphosate affects the mobilization of reserves and seedling morphology. Two tolerant and two herbicide-sensitive cultivars were submitted to germination, seedling length and reserve mobilization tests, including treatments with glyphosate solutions (0, 0.06 and 0.12 %). The hypocotyl / radicle ratio and the efficiency of conversion of reserves to seedlings were also verified. The data were submitted to analysis of variance and test of means. It was observed that the percentage of normal seedlings and length seedlings were affected due to the concentration of the herbicide in the treatments, being the consequences more pronounced for sensitive cultivars; the glyphosate-tolerant genotype and with the best physiological quality mobilized more reserves and was more efficient in converting biomass to seedlings; in morphology, the average length of the seedlings was reduced due to the herbicide, being the roots affected in such a way that they became smaller than the hypocotyls. The herbicide affects the morphology of the seedlings mainly the radicle, and the mobilization of the reserves discriminates the genotypes regarding tolerance to glyphosate.

“…of cereal rye, hairy vetch, and winter wheat seeds soaked in the 0.7 g L -1 glyphosate solution was reduced by 48%, 74%, and 45%, respectively, compared to the nontreated control (Table 4). Mondal et al (2017) reported 55% and 40% reduction in field pea seed germination with exposure to 3 and 4 mg L −1 glyphosate solution, respectively. Segura et al (1978) reported 6% and 23% reduction in Italian ryegrass seed germination and 19% and 20% reduction in germination of red clover with glyphosate at 4 kg ha -1 applied directly to covered and uncovered seeds, respectively, compared to the nontreated control.…”

Glyphosate is the most widely used herbicide in the United States; however, concern about increasing residues of glyphosate and its metabolite aminomethylphosphonic acid (AMPA) in soil is escalating. There is a lack of scientific literature examining the response of cover crops to soil residues of glyphosate or AMPA. The objectives of this study were to evaluate the impact of glyphosate or AMPA residues in silty clay loam soil on emergence, growth, and biomass of cover crops, including cereal rye, crimson clover, field pea, hairy vetch, and winter wheat, as well as their germination in a 0.07% (0.7 g/L) solution of AMPA or glyphosate. Greenhouse studies were conducted at the University of Nebraska-Lincoln to determine the dose response of broadleaf and grass cover crops to soil-applied glyphosate or AMPA. The results indicated that soil treated with glyphosate or AMPA up to 105 mg ae kg–1 of soil had no effect on the emergence, growth, above-ground biomass, and root biomass of any of the cover crop species tested. To evaluate the impact of AMPA or glyphosate on the seed germination of cover crop species, seeds were soaked in petri plates filled with a 0.7 g L−1 solution of AMPA or glyphosate. There was no effect of AMPA on seed germination of any of the cover crop species tested. Seed germination of crimson clover and field pea in a 0.7 g L−1 solution of glyphosate was comparable to the nontreated control; however, the germination of cereal rye, hairy vetch, and winter wheat was reduced by 48%, 75%, and 66%, respectively, compared to the nontreated control. The results suggested that glyphosate or AMPA up to 105 mg ae kg–1 in silt clay loam soil is unlikely to cause any negative effect on the evaluated cover crop species.
