Clear[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.

Researchers investigated how three common types of microplastics, polyethylene, polypropylene, and polystyrene, affect rice seed germination and early seedling growth. They found that microplastic exposure altered root development and shoot growth, with the effects varying by polymer type. The study raises concerns about how microplastic-contaminated agricultural soils could affect staple crop establishment and food production.
Influence of soil microplastic contamination and cadmium toxicity on the growth, physiology, and root growth traits of Triticum aestivum L.
Researchers grew wheat plants in soil contaminated with polyethylene microplastics, the toxic heavy metal cadmium, or both, finding that combined exposure caused the worst damage — shrinking root area, reducing gas exchange in leaves, and lowering key growth indicators. These findings raise concerns about crop yields in farmland where plastic pollution and heavy metal contamination overlap, which is increasingly common.
Unveiling the Effects of Polypropylene Microplastics (PP-MPs) on Growth Attributes and Antioxidant Defense System in Wheat (Triticum aestivum L.)
Scientists found that tiny plastic particles from everyday items like food containers can harm wheat plants when present in soil at higher levels, stunting their growth and reducing important nutrients. This matters because wheat is a major food crop worldwide, and if microplastics continue building up in farmland soil, it could affect our food supply and the nutritional quality of foods we eat. The study shows that plastic pollution isn't just an ocean problem—it's also threatening the crops that feed us.
Response of wheat (Triticum aestivum L. cv.) to the coexistence of micro-/nanoplastics and phthalate esters alters its growth environment
Researchers studied how wheat responds to co-existing stressors of microplastics and another soil contaminant, finding that combined exposure altered plant growth, physiological parameters, and grain quality compared to single-stressor exposures. The results highlight the importance of testing contaminant mixtures in agricultural soils.

Researchers found that microplastic particles altered wheat rhizosphere soil microbial community composition and function, with different polymer types inducing distinct shifts in bacterial diversity and nutrient cycling processes.
Effects of multiple microplastic types on growth of winter wheat and soil properties vary in different agricultural soils
Researchers tested the effects of ten different types of microplastics, applied individually and in combinations, on winter wheat growth across three agricultural soil types. They found that the same microplastic type could have drastically different effects depending on the soil, and that combined microplastic mixtures did not simply add up to the sum of individual effects. The study highlights the importance of considering both soil type and microplastic mixture composition when assessing agricultural impacts.
Effects of Polyethylene and Polystyrene Microplastics on Oat (Avena sativa L.) Growth and Physiological Characteristics

Investigation of the effects of polyethylene microplastics at environmentally relevant concentrations on the plant-soil-microbiota system: A two-year field trial
Researchers conducted a two-year field trial to study how polyethylene microplastics at environmentally relevant concentrations affect crops, soil, and microbial communities in a rice-wheat rotation system. They found that microplastics did not harm wheat growth but actually increased rice grain weight and plant height, while reducing soil nutrient levels including nitrogen and phosphorus. The study reveals that microplastics can alter soil bacterial communities and disrupt metabolic processes in ways that differ between crop seasons.
Phytotoxicity of polystyrene, polyethylene and polypropylene microplastics on tomato (Lycopersicon esculentum L.)
Researchers tested the effects of polystyrene, polyethylene, and polypropylene microplastics on tomato plant growth using hydroponic experiments at various concentrations. The study found that all three types of microplastics negatively affected seed germination, root growth, and plant development, with effects varying by plastic type and concentration. These findings suggest that microplastic contamination in agricultural settings could interfere with crop growth and food production.
The effects of microplastics on crop variation depend on polymer types and their interactions with soil nutrient availability and weed competition
Researchers investigated how different types of microplastics interact with soil nutrient availability and weed competition to affect crop growth. The study found that the effects of microplastics on plant performance depend on the polymer type and are modulated by fertilization levels and competition from weeds, suggesting that real-world agricultural impacts of microplastic pollution may be more complex than laboratory studies indicate.

Researchers used multi-omics analysis to investigate how nano- and microplastics of different types and sizes affect wheat plants and the bacterial communities in their root zone. They found that smaller nanoplastics caused more severe disruptions to plant gene expression and soil microbiome composition than larger microplastics. The study reveals that plastic particle size is a critical factor determining the severity of impacts on agricultural systems.
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.
Microplastic shape, concentration and polymer type affect soil properties and plant biomass

Soil texture modifies the impact of microplastics on winter wheat growth
Researchers grew winter wheat for 42 days in three soil textures contaminated with low-density polyethylene particles and polyester fibers to assess how soil type modifies microplastic toxicity. Soil texture significantly influenced outcomes—microplastics caused more root growth inhibition in silty loam and sandy loam soils by altering porosity and reducing nutrient and water availability, with polyester fibers causing an 85% reduction in root length in sandy loam.
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.
