Abstract
Pot experiments were conducted in the 2022 and 2023 seasons in a plastic greenhouse at the Experimental Station, Faculty of Agriculture, Zagazig University, Sharkia Governorate, Egypt. This study used common bean seeds (Phaseolus vulgaris L., cv. Bronco), the most prevalent cultivar in Egypt and susceptible to salt stress. In both seasons, seeds were planted on October 15 in plastic pots filled with 8 kg of air-dried clay soil. To keep four plants per pot, seedlings were thinned before the first irrigation. Three replicates were used in a split-plot, complete randomized block system, as the experimental design. No stress (control), 100 mM NaCl, and 150 mM NaCl treatments were used in the main plots. After full plant emergence, deionized water and selenium nanoparticles (Se-NPs) foliar spraying were applied to sub-main plot plants. During both seasons, salinity stress notably decreased the number of pods and green pod yield in each pot, as well as MSI; the membrane stability index, and RWC; relative water content compared to the control. However, Se-NPs overcame the negative impacts of salinity stress and produced more pods and total green pods per pot than the control. In addition, RWC, MSI, proline, and total soluble sugars were increased. It can be concluded that the use of Se-NPs in the common bean crop is an effective treatment in overcoming salt stress, leading to the possibility of producing this crop under high salinity conditions.
