ClearRisks 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.

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.

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.

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.

Researchers investigated the effects of polyvinyl acetate (PVA) microplastics at concentrations of 0%, 0.5%, 1%, 1.5%, and 2% on the germination, growth parameters, and nutrient content of horse gram, green gram, and chili grown in agricultural soil. Higher PVA concentrations reduced germination percentage, seedling length, and vigor index, and caused significant reductions in boron and sulphur concentrations alongside decreased soil pH and chlorophyll a levels.
