Saline water can be an alternative for the production of salt-tolerant forages. Thus, the objective was to evaluate the tolerance of alfalfa varieties to salinity, aiming at their inclusion in production systems that use irrigation water with high levels of salt or salinized soils. The experiment was conducted in a greenhouse, in a 3x5x3 factorial, three alfalfa varieties (LE-N4, Crioula and DK-192), five salinity levels (0; 3.5; 5.0; 7.0; 10. 5 and 14.0 dS m-1) and three cuts of the aerial part, with four replications. For irrigation management, lysimeters were installed. Fresh and dry plant biomass, chlorophyll, water use efficiency and enzymatic activity were analyzed. Increased salinity reduced fresh and dry biomass of shoots and roots, chlorophyll content and water use efficiency. Salinity altered the biochemical responses of alfalfa. DK-192 showed higher production of fresh and dry biomass of the shoot, while LE-N4 was more sensitive to saline stress, reducing production from the level of 7.0 dS m-1. Increased catalase activity in Crioula and DK-192 under saline stress contributed to the production of fresh and dry biomass of the shoot. |
