Abstract

Dehydration stress is the most significant abiotic factor that affects the growth and development of plants. In recent years, the use of engineered nanomaterials as a new solution against the destructive effects of water stress in plants has shown promising results. The present study was conducted to investigate the effect of carbon nanoparticles on the properties of bell peppers under water stress in greenhouse conditions in 2021, using a completely randomized design with three replications. The first factor was irrigation levels based on field capacity at three levels (100% FC, 75% FC and 50% FC). The second factor was the application of carbon nanoparticles at ten levels (without nanoparticles, fullerene100, 200, 1000 mg L-1, graphene 100, 200, 1000 mg L-1, multi-walled nanotube 100, 200 and 1000 mg L-1). The results showed that the foliar application of carbon nanoparticles helped mitigate the effects of water deficit stress on root dry weight, but did not moderate the negative impact of stress on reducing the number of fruits. However, the application of 200 mg L-1 of nanographene and 1000 mg L-1 of multi-walled nanotubes in the irrigation treatment increased the number of fruits to 100% FC compared to no nano application at the same irrigation level. The application of multi-walled nanotubes also increased the activity of catalase and peroxidase enzymes. However, the application of nanoparticles had varying effects on the activity of these enzymes at different irrigation levels.
