Glucoiberin and progoitrin were present in traces only.
The analysis of the oilseed rape sample revealed significant influence of the time of sampling on the concentration of progoitrin in the plant tissue of oilseed rape (p < 0.
The presence of progoitrin in the plants of oil radish and white mustard was below the limit of detection, which enables a wider spectrum of their use since the said aliphatic glucosinolate can cause negative effects in feeding of animals (VAN DOORN et al.
From the results of our study we can conclude that the concentration of progoitrin in cabbage hybrids is an important factor of selecting cabbage hybrids to be cultivated, since the concentration of the said glucosinolate in the two cabbage hybrids differed and caused different extent of injuries done by the studied harmful pests.
Stimulative influence of progoitrin on feeding of cabbage stink bugs was found in the medium-late cabbage samples (r = 0.
In Pactol, the predominant glucosinolates were progoitrin (8.
The second difference was the kind of predominant glucosinolates, being progoitrin, gluconapin, 4-hydroxyglucobrassicin and glucobrassicanapin in the former studies.
