It was evaluated in the germination and seedling stages the response to salinity induced with NaCl, Na2SO4 and NaHCO3 of three bean varieties which are the most produced in Nayarit, México. In a greenhouse, a completely random experimental design A×B×C was established with 63 treatments and five replicates. Factor A has seven levels of salt concentration (of 0.000-5760 g L-1), B with three bean varieties (Black, Pinto, Azufrado) and C three types of salt (NaCl, Na2SO4, NaHCO3). Germination, length, fresh and dry biomass of the stem and root were measured. For all types and concentrations of salt, compared to the threshold, germination significantly decreased on average 31% to 4.032 g L-1 and 49% to 5.760 g L-1, where Azufrado bean was the most resistant and NaHCO3 salt the one that decreased the most the percentage of germination. Stem length was significantly decreased on average 3.942 cm to 5.76 g L-1, Pinto bean obtained increased fresh and dry shoot biomass and at a concentration of 2.304 g L-1 of NaHCO3 none of the varieties survived; root length significantly decreased 10.532 cm to 5760 g L-1, Pinto beans produced more fresh and dry root biomass and NaHCO3 was the more affecting salt (Tukey, p≤ 0.05). As the salt concentration increased, the germination percentage, length, fresh and dry biomass of the stem and root decreased; the damage caused by salts was: NaHCO3>NaCl>Na2SO4.
