Abstract
Abstract In the present contribution, inulin coated ZnO nanoparticles (ZnO@inu NPs) were investigated for their potential application on crop production systems, by appraisal of their biostimulating effects on Vicia faba L (faba bean). Naked and coated ZnO NPs were synthesized according to purposely implemented eco-friendly protocols and characterized with multiple techniques to determine their crystallographic phase, average particle size, and degree of coating. Faba beans were grown in culture medium supplemented with NPs at 50 or 100 mg kg −1 , using ZnO NPs alone, inulin alone, a mixture of the two, or ZnO@inu NPs. Seed germination rate and biometric evaluations on seedlings were carried out, together with Zn localization in the plant tissues. Cellular and molecular effects were ascertained by analyses of photosynthetic pigments, cytotoxicity, genotoxicity, viability, induction of oxidative stress and tissue damage, antioxidant response, and modulation of gene expression. These combined studies indicated a potential role of ZnO@inu NPs in promoting growth and development of V. faba seedlings, acting at a post-germinative phase, probably by stimulating the stem cell mitosis. Finally, inulin as a coating agent for the ZnO NPs favored the bioavailability and adsorption of the nanomaterials into the plant tissues, without altering their bioactivity but mitigating any adverse side effect.
