How do microplastics affect the reproduction and survival of plants?
3 answers
Microplastics have negative effects on the reproduction and survival of plants. They can be deposited on flower stigmas by pollinators, leading to a decrease in seed production and the number of pollen tubes reaching ovaries. Microplastics can enter agroecosystems and accumulate in plants, causing pore space blockages on root surfaces, oxidative damage, and inhibiting nutrient and water uptake. They also affect the rooting ability of plants by altering soil bulk density and water-holding capacity, as well as reducing photosynthetic rate by interfering with the balance of plant chlorophyll a/chlorophyll b ratios. Microplastics can alter soil biophysical and chemical characteristics, affect enzymatic activities of plants, reduce root growth and seed germination, and accumulate and transport in plants facilitated by transpiration. Additionally, microplastics can affect plant communities by influencing community biomass and structure.
