Abstract

This study is a completely randomized research aimed to investigate the effects of zinc oxide, copper oxide and silicon dioxide nanoparticles on the control of grape rot (Vitis vinifera cv. Shahroodi) caused by Aspergillus niger, Botrytis cinerea and Penicillium expansum fungi at room temperature. The results of this research showed that the rotting of grapes which were infected by Aspergillus niger and Botrytis cinerea was greatly inhibited by spraying grape bunches with nano-zinc oxide and nano-silicon dioxide. The lowest rate of rotting in grapes infected with Penicillium expansum was also obtained by spraying grape bunches with nano-zinc oxide and nano-copper oxide. Nano-zinc oxide also increased total soluble solids in grape fruits inoculated with Aspergillus niger, although it had no significant effect on grapes inoculated with other fungi. Also, the results showed that the berry and stem of the grapes which were infected with fungi and treated with nano-zinc oxide had a better appearance compared to the fruits treated with other nanoparticles and the control. Furthermore, Fruits infected with Aspergillus niger and sprayed with nano-zinc oxide and nano-silicon dioxide had higher phenol contents compared to the samples treated with other nanoparticles and control . Anthocyanin content in grapes infected with Botrytis cinerea and treated with zinc oxide nanoparticles was significantly higher than controls and samples treated with other nanoparticles. In grape fruits infected with Aspergillus niger and Penicillium expansum, antioxidant activity was increased by spraying with nano-zinc oxide and nano-zinc oxide and nano-copper oxide.
