Klassifizierung von pflanzlichen Produkten aus ökologischem und konventionellem Anbau durch Messung sekundärer Pflanzenstoffe

Summary

The content of secondary plant compounds in plants is influenced by various environmental
factors. Cultivation and fertilization are factors which are characteristic for the
farming system organic or conventional. Within a german governmental funded project
(BÖL02OE170/F) carrot, maize and wheat samples from different farming systems
(defined trials and farm pairs) are differentiated and classified using their polyphenolic
and carotenoid contents and profiles, respectively.
The samples from organic farming could be differentiated from samples which were
conventionally grown as statistical significant for carrot and wheat samples in a two
year repetition. The samples could be classified by both, polyphenolic as well as
carotenoid profiles. The sum parameters only can not be applied for the differentiation
and classification of the samples. Factors like cultivar and site have a strong influence
on the classification. Therefore for the classification of the carrot samples according to
the farming systems land site must be included.
