| Abstract | ||
| Salt stress is among the most prevalent abiotic stresses which affect plant growth and yield. The application of nanoparticles can enhance growth and saline resistance of plants. The objective of this work was to mitigate the negative influence of salinity on the growth of two rice (Oryza sativa L.) genotypes using selenium nanoparticles (Se-NPs). Two rice genotypes (Sakha 101 and Giza 179) were subjected to salt stress (150 and 250 mM NaCl) and treated with Se-NPs (10 and 20 mg/L). Results revealed that the treatment of the two rice genotypes with 150 and 250 mM NaCl inhibited the growth traits including shoot length, root length, dry weights of root and shoot, fresh weight of shoot of both rice genotypes, as compared to control. However, Se-NPs (10 and 20 mg/L) treatment enhanced the growth criteria of both rice genotypes under salinity conditions. Overall, the application of Se-NPs improved the growth characteristics and minimized the damaging impact of salinity stress on rice plants. | ||
