Abstract
In vitro culture can provide a controlled and uniform system for studying the morphological and chemical effects of salt stress at the tissue development level. Explants cultured under a biotic 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 developments. Data reported in this study are summarized as follows: Increase salinity levels in MS medium to a decrease the number of leaves, number of branches and plant length of each explant. plantlets established from two varieties potato and developed on MS medium supplemented with NaCl proved to be tolerant to and 80 mmol Na Cl, in addition to the control treatment.
