Abstract
In 2006–2007 small radish was cultivated in a pot experiment. Foliar applications were applied twice with solutions of the following compounds: 1) control (water); 2) urea; 3) urea+molybdenum (Mo), 4) urea+Mo+benzyladenine (BA); 5) urea+Mo+BA+sucrose; 6) urea+Mo+BA+sucrose+salicylic acid (SA), 7) BA; 8) SA; and 9) sucrose. The above solutions contained following concentrations of compounds: urea 20 g dm−3, sucrose 10 g dm−3, Mo 1 mg dm−3, BA 5 mg dm−3 and SA 10 mg dm−3. In comparison with the control, spraying plants with the solution of urea+Mo+BA+sucrose and SA only caused an increase in leaf mass of one plant. Foliar applications did not have any effect on the yield of edible roots. When compared with the control, the use of sucrose resulted in a decreased content of nitrate (V) in leaves, while the application of urea+Mo+BA+sucrose led to elevated content of nitrate (V) in roots. In case of spraying plants with solutions containing urea (combinations no. 2–6) there was a tendency to increase ammonium (NH4 +) and nitrogen (N)-total content in leaves and roots, and increase in N uptake by leaves and by the whole plant but not by the radish roots. In combinations 7–9 we noted a decline in the level of ascorbic acid, and in combinations 2–6 there was a decrease in the content of soluble sugars in roots. In comparison with the control, an increase was observed in combinations 2 and 3, while in combinations 7–9 a decrease in the content of free amino acids in roots was observed. None of the combinations with foliar application caused any significant changes in the content of assimilative pigments in radish leaves and concentration of nitrate (III), dry matter in leaves and roots, the content of phenolic compounds, content of potassium (K), magnesium (Mg), calcium (Ca) extracted with 2% acetic acid in roots as well as free radical activity of radish roots.
