AbstractIn the years 2006–2007 radish ‘Opolanka’ cv. was grown in 60 × 40 × 20 cm containers, placed in the open field under a shade providing fabric. A loamy clay soil was used as a substrate. The following foliar nutrition treatments were applied twice: 1 – con-trol (spray with water), 2 – urea, 3 – urea + Mo, 4 – urea + Mo + BA, 5 – urea + Mo + BA + sucrose, 6 – BA (benzyladenine) and 7 – sucrose. There were used the following con-centrations of tested compounds: urea 20 g·dm-3, sucrose 10 g·dm-3, molybdenum (Mo) 1 mg·dm-3 and BA 5 mg·dm-3. Foliar nutrition treatments had a significant effect on aver-age mass of plant leaves and on concentration of soluble sugars and ascorbic acid in rad-ish roots. Plants treated with a mixture of urea + Mo + BA + sucrose featured the highest average mass of plant leaves. Radish roots of control plants and those sprayed solely with BA contained significantly more soluble sugars than roots of plants from other treatments. Spraying the plants with solutions containing only sucrose or only BA (treatments: 6 and 7) caused a significant reduction of ascorbic acid content in radish roots in comparison to other treatments. All the solutions used for foliar nutrition had no effect on radish roots mass and on mass of whole plants (roots + leaves). There were also not observed any sig-nificant changes in dry matter content of leaves and roots likewise in the content of phe-nolic compounds, phenylpropanoids, flavonols or anthocyanins in radish roots.
