The objective of this study was to evaluate the effect of the light emitting diode (LED) spectra on the antioxidant properties of sprouted wheat (Triticum aestivum L.), radish (Raphanus sativus L.), and lentil (Lens esculenta Moenh.) seeds. Lighting experiments were performed under controlled conditions (PPFD - 100 μmol m−2 s−1; 12 h photoperiod; 27°C). The(More)
Flavonoids are an important group of natural compounds, which can prevent coronary heart disease and have antioxidant properties. Hawthorn is a well known and widely used medicinal plant due to its cardiotonic activity. Previous studies refer mostly to the HPLC analysis of the flavonoids: vitexin, quercetin, hyperoside, oligomeric procyanidins, which appear(More)
Effects of short-term ozone (O3) fumigation on radish (Raphanus sativus L.) plants were examined in growth chambers under controlled environment conditions. Plants were exposed to 0 μg/m3 (reference), 80 μg/m3, 160 μg/m3 and 240 μg/m3 O3 concentrations for 7 h per day for five days. Day/night temperature was 21°C/14°C and photoperiod 16 h.

We report on the application of flashing amber (596 nm) light-emitting diodes (LEDs), supplemental to high pressure sodium lamps, for the cultivation of green sprouts, such as wheatgrass, barley grass, and leafy radish. The flashing light was found to significantly affect metabolism, thus conditioning the nutritional quality of the sprouts. In particular,(More)
The effect of nitrogen fertilizers on photosynthetic indices in two winter wheat (Triticum aestivum L.) varieties ‘Ada’ and ‘Seda’ was investigated in the experimental station of Lithuanian University of Agriculture during 2005–2006 and 2006–2007. The rates of fertilizers during wheat vegetation were as follows: N90, N120 and N150. In sowing time both(More)
