Abstract Greenhouse experiments were conducted to assess the effects of supplemental calcium in salinized soil on the response of germination and seedling growth of Salvadora oleoides, Decne. (Salvadoraceae). NaCl and CaSO4 center dot 2H(2)O were added to the soil and 0:0, 1:0, 1:0.25, 1:0.50, 1:0.75, 1:1, 1:1.25, and 1:1.50 Na/Ca ratios were maintained. Salinity significantly retarded the seed germination and seedling growth, but the injurious effects of NaCl on seed germination were ameliorated and seedling growth was restored with calcium supply at the critical level (1: 0.50 Na/Ca ratio) to salinized soil. Calcium supply above the critical level further retarded the seed germination and seedling growth due to the increased soil salinity. Salt stress reduced N, P, K, and Ca content in plant tissues, but these nutrients were restored by the addition of calcium at the critical level to saline soil. The opposite was true for Na+. The results are discussed in terms of beneficial effects of calcium supply on the seedling growth of Salvadora oleoides grown under saline conditions.
