ClearInfluence of Microplastics on Seedling Growth of Blackgram under Different Soil Types
A pot experiment tested the effects of polyethylene microplastics on blackgram seedling growth in two different soil types. Microplastics reduced germination rates, root and shoot growth, and chlorophyll content, with effects varying by soil type. The findings raise concerns about the impact of agricultural plastic waste on crop establishment and soil fertility.

Researchers tested different concentrations of polyethylene microplastics on blackgram plants and their surrounding soil. They found that higher microplastic levels significantly reduced plant growth, photosynthesis, and yield while also altering soil properties and microbial activity. The study demonstrates a dose-dependent relationship, with the most severe impacts occurring at the highest microplastic concentrations.

Researchers tested the effects of different microplastics on wheat seed germination and seedling growth and found that all treatments reduced plant development compared to controls. Polythene-containing microplastic treatments had the most negative impact, with significant reductions in both shoot and root length across wheat varieties.
Unveiling the effect of microplastics on agricultural crops – a review
This review examines how microplastics affect agricultural crops, covering impacts on seed germination, root growth, photosynthesis, and overall plant health. Most studies focused on polystyrene and polyethylene under controlled lab conditions, and the effects varied widely depending on plastic type, size, and concentration. The authors stress that more field-based research is needed to understand how microplastics actually behave in real farming environments.
Microplastics on the growth of plants and seed germination in aquatic and terrestrial ecosystems
This review examined the effects of microplastics on plant growth and seed germination in aquatic and terrestrial ecosystems, finding that microplastic presence can affect plant development through multiple mechanisms depending on polymer type, concentration, and the composition of the growing medium.
Risks of microplastics on germination and growth of pepper (Capsicum annuum L.) depending on the type, concentration, and particle size
Researchers tested how different types, concentrations, and sizes of microplastics affect pepper seed germination and seedling growth. They found that most microplastic treatments inhibited germination and that polyethylene terephthalate (PET) particles were generally the most harmful to seedling development. The study also revealed that larger microplastic particles tended to cause more oxidative stress in the plants, suggesting particle size plays an important role in toxicity.
Effect of polypropylene microplastics on seed germination and nutrient uptake of tomato and cherry tomato plants
Researchers tested the effects of polypropylene microplastics on tomato and cherry tomato seed growth in lab conditions. While microplastics did not significantly affect germination, they did alter how plants absorbed certain nutrients like potassium and calcium. This suggests that microplastic-contaminated soil could subtly change the nutritional quality of food crops, even if the plants appear to grow normally.
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.
Macro- and microplastic leachates show a slightly toxic effect on seed germination of cotton

Presence of High-Density Polyethylene Nanoplastics (HDPE-NPs) in Soil Can Influence the Growth Parameters of Tomato Plants (Solanum lycopersicum L.) at Various Stages of Development
Researchers grew tomato plants in soil spiked with high-density polyethylene nanoplastics at environmentally relevant concentrations, finding that the nanoplastics slowed germination, reduced root and shoot growth, and affected plant physiology at multiple developmental stages. Effects were dose-dependent and more pronounced at higher nanoplastic concentrations. As nanoplastics are now detected in agricultural soils through biosolid application and irrigation, this study raises concerns about the impact of nano-sized plastic contamination on food crop yields.
