Resumen:
The effect of soils amended with cnicin and onopordopicrin (major metabolites isolated from Centaurea diffusa and C. tweediei, respectively) on seed germination of tomato (Lycopersicum esculetum L.), lettuce (Lactuca sativa L.), wheat (Triticum aestivum L.) and honey weed (Leonurus sibiricus L.) was investigated. Both substances drastically reduced the germination of lettuce and honey weed. Since cnicin was active against some Gram (-) phytopathogenic bacteria, its effect on soil was investigated by calorimetric techniques. Cnicin at 0.1 mg/g-1 concentration selectively inhibited some soil microorganisms.
