- Abstract
It was evaluated in the germination and seedling stages the response to salinity induced with NaCl, Na 2 SO 4 and NaHCO 3 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 fi ve 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, Na 2 SO 4 , NaHCO 3 ). 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 signi fi cantly 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 NaHCO 3 salt the one that decreased the most the percentage of germination. Stem length was signi fi cantly 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 NaHCO 3 none of the varieties survived; root length signi fi cantly decreased 10.532 cm to 5760 g L -1 , Pinto beans produced more fresh and dry root biomass and NaHCO 3 was the more aff ecting 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: NaHCO 3 >NaCl>Na 2 SO 4 .
