Effects of salinity stress on seedling emergence and seedling growth characteristics were screened for four sunflower genotypes. Results revealed that there were significant differences for root length and shoot length, fresh weight and dry weight etc., under salinity. The differences among the genotypes for MDA and proline content were studied. The results suggest that, Olinda and Cleo genotypes were tolerate to salt stress and can be used for cultivation on saline soils for better yield.
