ClearEffects of Different Microplastics on Wheat’s (Triticum aestivum L.) Growth Characteristics and Rhizosphere Soil Environment
Researchers exposed wheat plants to multiple types of microplastics — including polyethylene, polypropylene, and polystyrene — at different concentrations to compare their effects on plant growth and physiological parameters. Different polymer types caused varying degrees of growth inhibition and oxidative stress.
Wheat (Triticum aestivum L.) seedlings performance mainly affected by soil nitrate nitrogen under the stress of polyvinyl chloride microplastics
Researchers evaluated the effects of polyvinyl chloride microplastics on wheat seedling growth and soil properties. They found that microplastics significantly reduced shoot biomass and soil nitrate nitrogen levels, suggesting that disrupted nitrogen availability may be the primary mechanism affecting plant growth. The study indicates that microplastic contamination in agricultural soils could impair crop development by altering soil nutrient dynamics.
[Effects of Microplastics on the Growth, Physiology, and Biochemical Characteristics of Wheat (Triticum aestivum)].
Wheat seedlings were grown in soils spiked with 100 nm and 5 μm polystyrene microplastics, with high concentrations (200 mg/L) significantly inhibiting root and stem elongation, reducing chlorophyll, and altering antioxidant enzyme activity, with smaller nanoplastics showing greater toxicity. The findings demonstrate that microplastic size influences phytotoxicity in a major agricultural crop.
Impact of polystyrene nanoplastics (PSNPs) on seed germination and seedling growth of wheat (Triticum aestivum L.)
Researchers exposed wheat seeds and seedlings to polystyrene nanoplastics and found that while germination rates were unaffected, root growth increased significantly compared to controls. However, the nanoplastics were taken up by the roots and transported to the shoots, reducing micronutrient absorption and altering key metabolic pathways related to energy and amino acid production. The findings suggest that nanoplastics can fundamentally change how crop plants grow and process nutrients.
Investigating the Impact of Microplastics Type of Polyethylene, Polypropylene, and Polystyrene on Seed Germination and Early Growth of Rice Plants
Researchers investigated how three common types of microplastics, polyethylene, polypropylene, and polystyrene, affect rice seed germination and early seedling growth.

Effect of microplastics and nanoplastics on cereal crops
This review summarized how microplastics and nanoplastics in soil affect cereal crops including wheat, rice, and maize, finding that even small amounts can inhibit seed germination, reduce root growth, and impair nutrient uptake. Microplastic contamination of agricultural soils poses a direct threat to global food security.
Macro- and micro- plastics in soil-plant system: Effects of plastic mulch film residues on wheat (Triticum aestivum) growth
Researchers studied how plastic mulch film residues, both conventional polyethylene and biodegradable types, affect wheat growth when mixed into soil. They found that both macro- and micro-sized plastic residues negatively impacted plant growth above and below ground, with effects varying depending on the plastic type and the presence of earthworms. The study highlights that agricultural plastic residues left in soil can meaningfully affect crop development and soil ecosystem health.
Polyethylene microplastic: impacts on ryegrass seed germination and seedling development
Researchers grew perennial ryegrass in hydroponic solution with polyethylene microplastics at six concentrations and three particle sizes (200 nm, 25 µm, 200 µm) and found that the smallest nanoparticles at the highest concentrations caused the greatest inhibition of germination, root growth, and seedling biomass.
Effect of Microplastics on the Germination and Growth of Terrestrial Plants
This review summarized studies on the effects of microplastics on the germination and growth of terrestrial plants, finding generally negative effects at high concentrations including reduced germination rates and root length. Effects varied by plant species, polymer type, and particle size, and the review highlighted limited data from realistic field exposures.
Joint toxicity of cadmium (II) and microplastic leachates on wheat seed germination and seedling growth
Researchers investigated how cadmium and chemical compounds that leach from microplastics jointly affect wheat seed germination and seedling growth. They found that microplastic leachates from PVC and polyethylene can interact with cadmium in complex ways, sometimes worsening and sometimes lessening the toxic effects on young wheat plants. The study suggests that the combined presence of heavy metals and microplastics in agricultural soils could pose risks to crop development.
Case Study Comparing Effects of Microplastic Derived from Bottle Caps Collected in Two Cities on Triticum aestivum (Wheat)
Wheat plants grown in soil containing microplastics derived from bottle caps collected in two cities showed reduced germination rates and root growth, with plastics from different cities producing different effects likely due to differences in additive composition, demonstrating that plastic source and formulation matter for ecotoxicological outcomes.
Sowing in Plastic Contaminated Soils: How (Micro)plastics Impact Seed Germination and Growth of White Mustard (Sinapis alba L.)
Laboratory and pot experiments with white mustard (Sinapis alba) exposed to low-density polyethylene microplastics found dose-dependent inhibition of seed germination, root development, and shoot growth, with higher MP concentrations causing greater plant stress.
Microplastics on the growth of plants and seed germination in aquatic and terrestrial ecosystems

Three typical microplastics affect the germination and growth of amaranth (Amaranthus mangostanus L.) seedlings
Researchers exposed amaranth seeds to three types of microplastics -- polystyrene, polyethylene, and polypropylene -- and found that the effects on germination and growth varied by plastic type, concentration, and particle size. Polyethylene and polypropylene microplastics inhibited shoot growth, while polypropylene caused the most root damage through reactive oxygen species accumulation. The study provides evidence that microplastic contamination in agricultural soils may pose risks to crop development.
