Seed proteins of eight species of the genus Suaeda (Chenopodiaceae) were compared by means of polyacrylamide disc gel electrophoresis. Different samples of the same species showed not less than 89% similarities, and geographical separation had no remarkable effect on seed protein patterns of the same species. Morphological heterogenity, that creates difficulties in infrageneric classificat...

salinity is known as one of the most challenging problems in aquaculture and agriculture. this issue has posed more difficulties to the shoreline of the persian gulf. halophyte plants with their high potentials of absorbing salinity from soil and water are able to enhance the biopurification process in the environment. hydroponic is a biointegrated food production method which links recirculati...
