Descriptif
The present investigation was undertaken to examine various aspects of salt tolerance mechanism in three halophytic plants differing in their habits. Trianthema monogyna L., is a subsucculent, prostrate annual ; Trianthema triQuetra Rottl. ex willd is a thin leaved species ; where as Ruppia rostellata koch, ex Reichb ; is a submerged seagrass, the only available species of its kind in this region. Leaves, stems and whenever possible roots of the plants, soils or water samples were collected from three habitats near Bhavnagar, New Port and Avania village. The work presented in the thesis assesses the toxic and osmotic effects of NaCl, KCl, MgC1 2 , CaC1 2 , Na 2S04 , MgS0 4 and seawater on seed germination of two species of Trianthema. It further examines relationship between the accumulation of organic and inorganic metabolites in vegetative organs with reference to changing levels of salinity in natural habitats.

The thesis has been organised into chapters on review of literature, material and methods, results, discussion and summary and conclusions. The supporting literature has been cited in the last chapter.
