Effect of drought and heat stress on polyamine metabolism and contents of phenolics, auxin and abscisic acid in Norway spruce somatic embryos

The aim of the project was to evaluate the alterations in polyamine metabolism and in the levels of hydroxycinnamic acids, flavonoids and stilbenes in the stress response of somatic embryos of Norway spruce to drought and high temperature. The determined contents of abscisic acid and auxin contributed to understanding the abscisic acid-auxin cross-talk in the response to stress. The extent of lipid peroxidation (as indicated by MDA levels) in stressed somatic embryos was also investigated. Histochemical tests for the presence of polyphenolic substances on embryo sections after the exposure of somatic embryos to UV-B completed the biochemical analyses.
