Résumé :

Glycine max L. tissue cultures were initiated on different media supplemented with appropriate plant growth regulators that specifically induce the formation of callus, root, or shoot primordia. Exogenously applied hormones resulted in important changes in both Lox and HPO decomposition activity. Lox activity was higher in extracts from tissues cultured in medium supplemented with NAA or 2,4-D, while a lowest activity was recorded in extracts from cultures treated with BA. 13-HPOD was cleaved by all tested extracts, while 13-HPOT and 9-HPOD were cleaved exclusively by extracts from tissues cultured in the presence of BA.
