| Abstract | ||||
| This study was conducted to evaluate the effects of nano-silicon (NSi) in mitigating the negative impact of salinity on the growth and yield of two wheat (Triticum aestivum) cultivars. Two wheat cultivars, Giza 171 and Shandawel 1, were subjected to foliar applications of nano-silica at five concentrations (0, 50, 100, 200, and 400 mg/L) under two different soil conditions: normal and saline. The experiment was carried out in pots under greenhouse conditions at the Faculty of Science, El-Mansoura University, El-Dakahlia Governorate, during the 2020/2021 growing season. The saline soil was collected from Gabel El-Nargis sand dunes in Baltim, Kafr El-Sheikh Governorate, while the control soil was obtained from farmland in El-Mansoura. The study assessed yield components, total carbohydrates, protein content, and silica accumulation in the grains. Results indicated that salinity had detrimental effects on yield and its components, as well as on total protein content in grains, while total carbohydrates and silica levels increased under saline conditions. The application of NSi significantly alleviated the harmful effects of salt stress by improving spike length and weight, the number of spikelets per spike, the weight of 100 grains, and total protein content. Furthermore, the total carbohydrate and silica content in grains increased under salinity stress and was further enhanced by NSi application. These findings suggest that NSi application is beneficial in improving salt tolerance in wheat, thereby mitigating the negative effects of salinity stress and enhancing both yield and grain composition. | ||||
