Under standard cultivation conditions, Norway spruce somatic embryos (SEs) accumulate polyphenolic compounds mostly in the root cap. In response to UV-B, the accumulation of polyphenolics increases in protodermal cells and subprotodermal cortical cells and idioblasts in hypocotyl and cotyledons where they can attenuate UV-B stress. To quantify polyphenolic compounds accumulated in somatic embryos on the histological level resin sections were prepared, stained with Toluidine Blue.
