Wpływ herbicydów i zróżnicowanego nawożenia NPK na zawartość ß-karotenu w liściach bobiku (Vicia faba L. ssp. minor) [Effect of herbicides and various NPK dosage on ß-carotene content in the leaves of Vicia faba L. ssp. minor]

Effect of herbicides Afalon (linuron), Aretit (dinoseb acetate), Gesatop 50 (simazine) was tested concemitantly with two NPK fertilization levels (N - 0, P2O5 - 36 kg/ha, K2O - 60 kg/ha and N - 70 kg/ha, P2O5 - 72 kg/ha, K2O - 120 kg/ha) on the ß-carotene content of field bean leaves. The carotenoids content was determined by thin-layer chromatography on magnesium oxide in the system petroleum ether: acetone (88 : 12 v/v). An increase of ß-carotene content in the field bean leaves at the flower-bud formation stage was found, after application of above mentioned herbicides and high dosage NPK fertilization levels. No influence of herbicides and mineral fertilization on the (ß-carotene content in the plant leaves could be demonstrated at the full pods stage.
