Salinity represent the main factor which limits agricultural productivity and result from poor management of irrigation. This, put questioned the future of agriculture in a context in which areas affected by excess salinity they have come to be for over 200 milion hectares right across the planet and approximate 400.000 in Romania. At the moment, it is estimated that about 20% from irrigated surfaces from the world are affected by salinity and this trend grow with climate change and with the use of excess irrigation. From an agronomic point of view, salinity disrupts growth and plant physiology. Phaseolus vulgaris L. it is a sensitive species to the salts. For this reason, the purpose of work was determining the effect of excess NaCl on the dynamics of the chlorophyll content index and foliar stomatic conductivity of 7 bean genotypes, collected from saline soils, from north-east of Romania, as an indicator of salt stress tolerance.
