Abstract
In a solution culture experiment, seven cotton genotypes were examined for comparative performance at three NaCl concentrations viz. control (without salts), 100 and 200 mol m-3 NaCl with four repeats in a completely randomized statistical fashion. The plants were harvested four weeks after the imposition of the NaCl salinity stress. Shoot fresh and dry weights and shoot and root lengths were decreased by increasing levels of NaCl salinity. The greatest reduction was observed at 200 mol m-3 NaCl salinity stress significantly. K+ : Na+ ratio of different genotypes differed significantly at both NaCl concentrations. Differences were observed among genotypes with regard to growth and salinity tolerance
