(Table 2). Solanum lycopersicon showed a reductionin shoot and root biomass (ca. 35% and 22%, respectively) undersalt treatment, while in S. pennellii, the shoot biomass showedless reduction (ca. 21%) and no significant change in root biomass(Table 2). A similar trend was observed for leaf area, where salttreatment reduced the leaf area of both species, with a morepronounced decrease (ca. 39%) in S. lycopersicon (Table 2). The phys-iological responses varied depending on the salt tolerance of thetwo species. In S. lycopersicon, relative water content showed adecrease of 25% after one week of salt stress, whereas the salt-stressed S. pennellii was able to maintain a leaf relative watercontent comparable to control plants
