Abstract
BACKGROUND
The aim of this 3-year study was to investigate the effect of different celeriac cultivation strategies on the content of naturally occurring toxicants furanocoumarins, represented by psoralen, bergapten, xanthotoxin and isopimpinellin. The products from organic farming in which anaerobically fermented pig slurry was used were compared against those obtained from other treatment systems: mineral, combined and non-fertilised.
RESULTS
The average levels of furanocoumarins for all 3 years (determined by gas chromatography-mass spectrometry) in varieties Albin and Kompakt were 2.6 mg kg⁻¹ and 10.2 mg kg⁻¹, respectively. In all crop years higher levels were found in variety Kompakt. By using linear discriminant analysis it was possible to separate the whole data set according to variety from 85.7%, in individual crop years the recognition ability was more than 90%. According to the crop year, it was possible to separate tested samples from 70.8%, for individual variety the separation was 100%.
CONCLUSIONS
The method of fertilisation did not have a significant effect on the levels of plant secondary metabolites, furanocoumarins. The climatic conditions, in particular the growing periods and the celeriac variety, had an important role in the occurrence of furanocoumarins.
