Abstract

Salinity stress had a direct impact on rice (Oryza sativa L.) growth and physiological features throughoutthe early stages of development. The current study aimed to investigate the influence of Zinc oxidenanoparticles (ZnO-NPs) in the rice germination stage during salinity stress because the germination andseedling stage is critical for the correct development and growth of plants. The different concentrations ofNaCl 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 ratein rice during salinity stress. We conducted our experiment in a landrace of rice Kargi and salinity tolerancerice variety CSR 30. The current study’s findings reveal that ZnO NPs have a significant effect in reducingsalt stress during rice germination.
