Explants of two potato varieties (Spunta and Agria)cultured under abiotic stresses such as salinity has been examined through morphological and chemical analyses. This has led to much information through studies of plants subjected to salt treatments. The aim of the work reported in this study, was to evaluate two varieties of Potato (Spunta and Agria) for their competence for Sodium Chloride (NaCl) Within the (0, 10, 20, 40, 60, 80 mmol) tolerance and tissues dIn vitro culture can provide a controlled and uniform system for studying the morphological and chemical effects of salt stress at the tissue development level.

The data reported in this study are summarised as follows: Increase salinity levels in the media leads to a decrease the number of leaves, number of nodes and plant length of each explant. Plantlets date established from two varieties potato and developed on MS medium supplemented with and without NaCl, proved to be tolerant till80 mmol NaCl. The accumulation of sodium and osmolarity in tissues cells increased significantly with a positive correlation according to high concentrations from 0 to 100 mmol NaCl.التغيرات الخلوية
