Whole plant growth, foliage mineral content, and leaf gas exchange were measured on  Mammea americana  seedlings exposed to salinity ranging from 0 to 8 dS·m –1  to determine relative tolerance of this species. In one study, growth measured as leaf area, trunk cross-sectional area, and total dry mass was reduced by 23 weeks of exposure to salinity. Growth of plants exposed to 8 dS·m –1  was   ≈30% below that of control plants. Leaf gas exchange was reduced by salinity to a greater degree than the growth variables. Stomatal conductance of plants exposed to 8 dS·m –1  was ≈70% below that of control plants. Plants exposed to 8 dS·m –1  exhibited a seven-fold increase in leaf chloride and 13-fold increase in leaf sodium compared to the control plants. In a second study, 8 weeks of exposure to 8 dS·m –1  reduced net CO 2  assimilation and apparent quantum yield to ≈50% of the values for the control plants. Dark respiration was not influenced by salinity. The results indicate that  Mammea americana  is moderately sensitive to salinity stress.
