Abstract

  Due to natural processes and anthropogenic, the soil is rapidly contaminated with the continuous accumulation of salts, which affects the crop production worldwide. Therefore, it is essential to exploit the modern techniques to improve the tolerant of plants to salinity. The present experiment was designed to study the effect of SA on (1) seed germination parameters and (2) physio-biochem ical changes in wheat seedlings under NaCl stress. NaCl exhibited reduced germination parameters (germination %, vigor index and mean germination time), seedlings height, content total chlorophyll and total carbohydrates and increased production of reactive oxygen species [detected using the fluorescent probe 2',7'-dichlorodihydrofluorescein diacetate (DCF-DA) for H2O2 and dihydroethidium (DHE) for O2•-] in roots, content of malondialdehyde and proline, and chlorophyll degradation. However, wheat seedlings treated with SA showed increased seed germination traits and plant height by increasing proline and total soluble carbohydrates by suppressing ROS formation in roots and leaf-chlorophyll degradation.
