Growth and nutritional status as well as ascorbic acid oxidase and peroxidase activities in cucumber (Cucumus sativus L. var. Salprita) plants grown under NaCl salinity were studied. The growth was decreased with increase of NaCl level. Highly significant negative correlations were found between salinity level and the uptake of all determined elements except that of manganese (Mn) in the shoots. Under salinity stress conditions, potassium (K) and calcium (Ca) were found to migrate from roots to shoots, while iron (Fe) tends to accumulate in the roots and uptake of zinc (Zn) and copper (Cu) was impaired. Potassium and phosphorus (P) concentrations were dramatically decreased as the level of NaCl was increased, meanwhile magnesium (Mg) showed a slight decrease and Ca concentration even increased in the shoots. Micronutrient concentrations showed different trends as the salt concentration increased. Iron (Fe) was severely decreased in the shoots, zinc (Zn) was decreased in the roots, Copper (Cu) was decreased in both shoots and roots while manganese (Mn) was increased in the shoots. Nutrient concentration ratios were disturbed. P/K ratio was deviated negatively in the shoots and positively in the roots of salt treated plants as compared to control. However, K/Mg was deviated positively in the shoot and negatively in the root. K/Zn was negatively deviated in the root at high salt level and positively in the shoot under the low level. Fe/Zn was negatively deviated from control plants in the shoots and roots under low salt level and positively in the roots of the plants grown under the high level. Ascorbic acid oxidase and peroxidase activities in cucumber leaves were severely inhibited as the salt level increased in the root medium. Thus, activities of these enzymes can be used as indicators for salt stress conditions.
