Abstract

Salinity stress had a direct impact on rice (Oryza sativa L.) growth and physiological features throughout the early stages of development. The current study aimed to investigate the influence of Zinc oxide nanoparticles (ZnO-NPs) in the rice germination stage during salinity stress because the germination and seedling stage is critical for the correct development and growth of plants. The different concentrations of NaCl and ZnO NPs (T1 -60 mM NaCl, T2 -80 mM NaCl, T3 -100 mM NaCl, T4 -60 mM NaCl+50 ppm ZnO NPs, T5 -80 mM NaCl+50 ppm ZnO NPs and T6 -100 mM NaCl+50 ppm ZnO NPs) improve the germination rate in rice during salinity stress. We conducted our experiment in a landrace of rice Kargi and salinity tolerance rice variety CSR 30. The current study’s findings reveal that ZnO NPs have a significant effect in reducing salt stress during rice germination.
