Zinc nano particles for enhancing salinity stress resilience in wheat (Triticum aestivum L.)

This study explored zinc nano particles (ZnNPs), crafted from Crassula multicava leaf extract, to bolster wheat’s resilience against salt stress. These ZnNPs were characterized to be found mostly spherical and polydispersed. In a pot experiment, wheat (PBW 226) was exposed to salinity levels and treated with ZnNPs at tillering (30 DAS), booting (58 DAS), and flowering stages, with untreated, non-stressed plants as controls. ZnNPs markedly enhanced all growth and yield traits, with plants at 25 mM NaCl showing the most significant improvements (p less than 0.05) over controls. This study highlights ZnNPs’ promise as a sustainable solution to mitigate salinity stress, supporting wheat production and global food stability.
