RESPUESTA DE PHASEOLUS VULGARIS A LA SALINIDAD GENERADA POR NACL, NA2SO4 Y NAHCO3
The response to salinity induced with NaCl, Na2SO4 and NaHCO3 was evaluated in the germination and seedling stage of three bean varieties that are those with the highest production in Nayarit, Mexico. In the greenhouse, a completely randomized A × B × C experimental design was established with 63 tr...

| Resumo: | The response to salinity induced with NaCl, Na2SO4 and NaHCO3 was evaluated in the germination and seedling stage of three bean varieties that are those with the highest production in Nayarit, Mexico. In the greenhouse, a completely randomized A × B × C experimental design was established with 63 treatments and five repetitions. Factor A had seven levels of salt concentration (from 0.000 to 5.760 g L-1), B three varieties of beans (Black, Pinto, Sulfur) and C three types of salt (NaCl, Na2SO4, NaHCO3). The germination, length, fresh and dry biomass of the stem and root were measured. For all salt concentrations and types, with respect to the threshold, germination decreased significantly on average 31% to 4,032 g L-1 and 49% to 5,760 g L-1, where the Azufrado bean was the most resistant and the NaHCO3 salt the one that most decreased the percentage of germination. The stem length decreased significantly on average 3,942 cm to 5.76 g L-1, the Pinto bean obtained higher fresh and dry stem biomass, and at a concentration of 2,304 g L-1 of NaHCO3 no variety survived; root length decreased significantly 10,532 cm to 5,760 g L-1, Pinto beans produced higher fresh and dry root biomass and NaHCO 3 was the salt that affected the most (Tukey, p≤ 0.05). As the concentration of salts increased, the percentage of germination, length, fresh and dry biomass of the stem and the root diminished; the damage of the salts was NaHCO3> NaCl> Na2SO4. |
