Effects of Microplastics on Germination and Seedlings Growth of Wheat (Triticum aestivum L.)
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.
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. 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.
Effect of polyethylene microplastics on seed germination of Blackgram (Vigna mungo L.) and Tomato (Solanum lycopersicum L.)
Researchers tested how polyethylene microplastics affect seed germination in blackgram and tomato plants, finding that higher concentrations temporarily slowed germination and root growth in blackgram within the first 24 hours, but plants largely recovered by 48–72 hours. The effects were dose-, species-, and time-dependent, suggesting microplastics can cause short-term harm to crops but may not cause permanent damage at these concentrations.
The Effect of Microplastics with Different Types, Particle Sizes, and Concentrations on the Germination of Non-Heading Chinese Cabbage Seed
Five microplastic types were tested on non-heading Chinese cabbage seed germination, finding PVC and PET had the greatest inhibitory effects on germination, while PVC and PP promoted growth of germinated seeds at certain concentrations.
Physiological analysis and transcriptome profiling reveals the impact of microplastic on melon (Cucumis melo L.) seed germination and seedling growth
Researchers examined how polyvinyl chloride microplastics affect melon seed germination and seedling development. They found that low to medium concentrations of microplastics significantly reduced germination rates and stunted young root growth, while also disrupting gene expression related to plant stress responses. The study provides early evidence that microplastic contamination in agricultural soils may impair the growth of economically important crop plants.
Effects of nano- & microplastics on terrestrial plants are ubiquitous and widespread: a systematic review
This systematic review finds that nano- and microplastics have widespread negative effects on plants, including reduced germination, stunted growth, and biochemical stress responses. Since plants form the base of our food supply, these findings suggest that microplastic contamination in agricultural soils could affect crop health and potentially the quality of food we eat.
Microplastic exposure reduces seed germination in a coastal plant
Researchers tested how microplastic exposure affects seed germination in a coastal dune plant using environmentally realistic, weathered microplastic particles. They found that microplastics significantly reduced germination rates compared to controls. The study highlights that wild plants in coastal habitats, which are among the most plastic-polluted environments on land, may face real reproductive challenges from microplastic contamination.
Effects of polyethylene terephthalate microplastic on germination, biochemistry and phytotoxicity of Cicer arietinum L. and cytotoxicity study on Allium cepa L
Researchers studied the effects of polyethylene terephthalate (PET) microplastics on chickpea germination and onion root tip cells at concentrations ranging from 50 to 1,000 mg/L. The study found a sharp decrease in germination rates along with biochemical changes and cytotoxic effects at higher microplastic concentrations. Evidence indicates that PET microplastics in soil can negatively affect both plant development and cellular processes.
