Lead (Pb) is one of the noxious trace metal element (TME) contaminants in the environment. In this work, we conducted a comparative physiological response study through some germination parameters between four cereals (Triticum durum, Triticum aestivum, Hordeum vulgare, and Zea mays) grown on a nutrient solution for 10 days and treated with three increasing levels of lead acetate (0.15, 0.3, and 0.6 g/L) in order to evaluate the impact of different lead concentrations on the germination capacity of these species. The results showed that lead has an abiotic stress effect on the four varieties examined at 0.3 g/L and 0.6 g/L. We recorded a significant to very highly significant effect in all the parameters studied. In the underground parts, in particular, a highly significant reduction in precocity of germination was recorded in Triticum durum, Triticum aestivum, Hordeum vulgare, and Zea mays. There was also a highly significant to very highly significant decrease in germination percentage in durum wheat, soft wheat, and maize. Under the most severe stress conditions (0.6 g/L), the barley variety showed stress tolerance with a germination rate of 92%. According to the findings of this study, the varieties examined can be grouped into two categories: variants that are susceptible to metal stress (Triticum durum, Triticum aestivum, and Zea mays) and varieties that are tolerant to lead exposure (Hordeum vulgare).

“…Previous research has demonstrated plant growth inhibition when the soil Pb concentration is high, possibly due to the adsorption saturation of Pb by the cell wall, leading to more mobile Pb reaching the protoplasm ( Niu et al, 2012 ; Zhou et al, 2017 ). Bahram et al ( Gholinejad et al, 2020 ) found that the content of photosynthetic pigments, biomass, seed vitality and emergence rate of non-tolerant ryegrass plants were negatively affected by a soil Pb concentration of 250 mg kg −1 . Jin et al (2016) also reported reduced growth rate in non-tolerant ryegrass in response to 300 mg kg −1 soil Pb concentration.…”

Exogenous addition of IAA has the potential to improve the metal tolerance and phytostabilization of plants, but these effects have not been systematically investigated in naturally tolerant plants. Ryegrass (Lolium perenne L.) is a typical indigenous plant in the Lanping Pb/Zn mining area with high adaptability. This study investigated the phytostabilization ability and Pb tolerance mechanism of ryegrass in response to Pb, with or without foliar spraying of 0.1 mmol L−1 IAA. The results indicated that appropriate IAA treatment could be used to enhance the phytostabilization efficiency of naturally tolerant plants. Foliar spraying of IAA increased the aboveground and belowground biomass of ryegrass and improved root Pb phytostabilization. Compared to Pb-treated plants without exogenous IAA addition, Pb concentration in the shoots of ryegrass significantly decreased, then increased in the roots after the foliar spraying of IAA. In the 1,000 mg kg−1 Pb-treated plants, Pb concentration in the shoots decreased by 69.9% and increased by 79.1% in the roots after IAA treatment. IAA improved plant growth, especially in soils with higher Pb concentration. Foliar spraying of IAA increased shoot biomass by 35.9% and root biomass by 109.4% in 1,000 mg kg−1 Pb-treated plants, and increased shoot biomass by 196.5% and root biomass by 71.5% in 2,000 mg kg−1 Pb-treated plants. In addition, Pb stress significantly decreased the content of photosynthetic pigments and anti-oxidase activities in ryegrass, while foliar spraying of IAA remedied these negative impacts. In summary, foliar spraying of IAA could increase the biomass and improve the Pb tolerance of ryegrass.

“…The strong resistance, wide ecological values and certain tolerance to HMs contaminated soil of Perennial ryegrass are reported, such as a certain ability to tolerate or accumulate Cu, Pb, and Zn [ 13 ]. Gholinejad et al [ 14 ] showed that perennial ryegrass had a strong capacity to accumulate Pb and could be suitable for growth in HMs polluted soil, in which concentrations of Pb was up to 1000 mg kg −1 . Huang et al [ 15 ] all reported that 'aubisque', a perennial ryegrass variety from Canada, is more tolerant to Cd than 'overseederii'.…”

Cadmium (Cd) and arsenic (As) exist simultaneously in soil environment, which poses a serious threat to the safety of agricultural products and forage production. Four Perennial Ryegrass (Lolium perenne L.) cultivars with different accumulation characteristics (ʻNicaraguaʼ, ʻVenusʼ, ʻExcellentʼ and ʻMonroʼ) were selected as the material for pot experiment. The coupled responses of key components and related enzyme activities under combined stresses of Cd and As were investigated. key components contents include Non protein sulfhydryl (NPT), glutathione (GSH) and phytochelatins (PCs). The related enzyme includes (superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), γ-glutamylcysteine synthetase (γ-ECS), glutathione synthetase (GSS), phytochelatin synthetases (PCSase) and arsenate reductase (AR). The results showed that Cd contents of perennial ryegrass were higher than those of As contents with TFCd/As < 1. Cd and As contents in roots were in the higher proportion than those in shoots. Compared to control, POD activities increased by 2.72 folds under 120 mg kg−1 As treatment. The contents of PCs increased by 5.68 folds under 120 mg kg−1 As treatment. Under combined Cd and As stress, the MDA contents and antioxidant enzyme activities of ʻVenusʼ were higher than those of ʻNicaraguaʼ. ʻNicaraguaʼ, a high accumulation cultivar. Under the combined stresses of Cd and As, the enzyme activities and the key components were significantly correlated (P < 0.05) with the contents of Cd and As. The tolerance to Cd and As was improved with increase in GSH and PCs contents and γ-ECS, GSS, PCSase and AR activities. In conclusion, the antioxidant enzyme system and key resistant substances of perennial ryegrass have important and antagonistic effects on Cd and As stresses.
