Phaseolus vulgaris L. is a species sensitive to salts. For this reason the purpose of the work was determining the effect of excess NaCl on the rate of dehydration and bound water content, to 7 bean genotypes, collected from saline soils, from north-east of Romania. Overall objective of the study it is to contribute to a better understanding of the physiological mechanisms involved in tolerance to saline stress of species Phaseolus vulgaris L. and identify local bean populations tolerant to salinity. These forms can be used for improvement morphological traits involved in achieving production capacity. The results showed that after 15 days of treatment, saline concentration did not influence significant the tracking parameters. Instead, after 30 days of treatment, the influence of salinity is very significant, which it demonstrates the adaptability present by these local genotypes, over a long period of time.
