Abstract
With the increased use of nanotechnology in almost all aspects of life, there is an increasing chance of risk of plants exposure to different nanoparticles (NPs). However, the studies on its potentially harmful effects in the cultivated crops are not well studied yet. Therefore, the authors aimed to study the effects of tin (Sn) NPs on the growth and physiological aspects of Zea mays . Thus, they exposed the maize seedlings to different concentrations of SnNPs for 2 weeks, and results revealed that the SnNPs at the studied concentration were not able to affect the seedling growth at a significant level. However, it induced the oxidative stress which was confirmed by increased guaiacol peroxidase, polyphenol oxidase and catalase activity. They also discussed that exposure duration, aggregation and concentrations were contributing factors in NPs mediated metal toxicity.
