ABSTRACT
This study determines the genetic diversity of 20landraces and released cultivars of tomato collected from Market places and research institutes in Nigeria. Ion homeostasis and cytotoxic sequestration significantly (P>0.05) affected by concentration of salt in a concentration dependent manner. Accumulation of Na+, Cl-, K+ and Ca2+ ions increased in salt treated groups (30 and 60 mg/L of NaCl) as compared to controls. Potassium ion uptake was salt concentration dependent in all cultivars; the magnitude of Na+/K+ levels is lower in released cultivars than in landraces cultivars. It can be concluded from these findings that Na+ was compartmentalized both in tomato by membrane transporters and that low level was a good indicator of salt tolerant in tomato genotype studied.
