To explore the effects of microplastics (MPs) on the growth of vegetables, taken two commonly detected MPs (i.e. polyethylene (PE) and polypropylene (PP)) in soils of cherry radish (Raphanus sativus L. var. radculus pers) as the target contaminants, selected cherry radish as the tested materials, the effects of the tested MPs on the growth of radish were preliminary studied based on the seed germination test and the soil culture experiment. The results showed that PE and PP had no effect on the germination rate of radish seeds. The addition of MPs to the water had no significant effect on the bud length of seedlings, except for the treatment with 5 g·L^-1 of PP; the two tested MPs attached to the radish roots, and significantly (P < 0.05) inhibited the growth of the root, moreover, this inhibitory effect enhanced with increasing MPs concentrations and decreasing MPs particle sizes. PE and PP had no significant impact on the photosynthetic pigment content in the cherry radish, furthermore, PE induced negligible impacts, while PP significantly (P < 0.05) decreased the radish biomass, which indicated that the effects of MPs on the radish growth were related to MPs types. A plausible explanation is that PE and PP have various effects on soil structure and/or fertility, thereby resulting in different performances of radish biomass after exposure to PE and PP.
