摘要：
An experiment with tomato plants was carried out in order to study the resistance of this plant to saline irrigation. Seeds were treated with saline water (a solution of 30 g/L of NaCl) previously to the germination (treatment PG) and in the seed bed of peat, previously to the transplant (PT), with water of 0.7-1.5 (current water), 2.5 and 4.5 mS/cm of electrical conductivity reached by adition of NaCl. Plants were cultivated in a calcareous soil under greenhouse conditions and irrigated during the period of cultivation with saline water of 0.7-1.5 (low salinity), 2.5 (medium salinity) and 4.5 (high salinity) mS/cm. Growth (length and fresh weight of plant stem, branches and leaves) and nutrient content (mineral analysis) was studied. The results showed that plants treated with saline water were not affected by the highest level of salinity in the same way that those not treated. The nutrient content in the leaves was affected but specially the concentration of Na.
