Lettuce (Lactuca sativa L.) tolerance to salinity
Part III. Metallic microelements and sodium content in plants
Summary.

The main aim of the conducted studies was estimation of nutrient solution with increasing salinity level: I (EC 1.60 mS·cm-1), II (EC 2.50 mS·cm-1), III (EC 3.50 mS·cm-1), IV (EC 5.10 mS·cm-1) on the changing microelement content in aboveground plants parts, concentrating on butterhead lettuce tolerance to increasing salinity level. Along with increasing salinity level of nutrient solution, levels of iron, manganese, zinc, copper and sodium were increasing. The nutrient solution salinity levels significantly influenced the iron, manganese, zinc, copper and sodium content in lettuce head – and moreover, on iron, manganese, zinc and sodium contents in outer leaves. The nutrient solution salinity has no significant influence on the copper content in case of outer leaves. The varieties have no significant influence on iron, manganese, copper and sodium in lettuce heads, but it influences the zinc content. In case of lettuce outer leaves the variety significantly differentiated the content of iron, manganese and sodium. The symptoms of toxicity of excessive salinity nutrient solution levels range from 1.60 to 5.10 mS·cm-1, have not been found on plants.

Key words: Lactuca sativa L., microelements, nutrient content, salinity, tolerance
