Abstract: Seedings of Triticum aestivum cvs. Lyallpur-73, Pak-81 and Lu-26-S were grown in solution culture at varying concentration of NaCl for 8 days. Increasing concentrations of NaCl reduced the size of apical meristem and caused the most distal root hair to form closer to the root tip in all the cultivars. Although the position of the first root hair from the root cap boundary was reduced by salinity, yet there were comparatively little differences between these Pakistani Wheat cultivars in response to NaCl, thus in these studies the relative positions of root hairs is not a good discriminating character for assessing the salt tolerance.
