| Description
| - Cílem práce bylo ověřit, zda filtrát sekundárně patogenní houby Ascocalyx abietina, indukuje u embryogenních kultur smrku ztepilého změny v obsahu fenolických látek , což by bylo indikátorem obranné reakce na napadení patogenem. Zaměřili jsme se na akumulaci rozpustných a stěnově vázaných fenolických látek, stilbenů a na aktivitu extracelulární peroxidázy. Změny vyvolané filtrátem se projevili významně ve zvýšení stěnově vázaných fenolických kyselin (o 130 %) a rozpustných fenolických glykosidů až o 65%.Vliv filtrátu se neprojevil významně v aktivitě extracelulární peroxidázy.Z výsledků vyplývá, že filtrát houby Ascocalyx abietina vyvolává totožné změny v sekundárním metabolismu smrkových buněk jako houbová infekce.

- The aim of this work was to identify whether the Ascocalyx abietina culture filtrate has the ability to induce changes in the contents of phenolic substances that might be indicative for the disease response of Norway spruce (Picea abies). We focused on the accumulation of soluble and cell wall-bound phenolics, stilbenes as well as extracellular peroxidase activities elicited in the embryogenic cell cultures of Norway spruce by A. abietina culture filtrate. Treatment of spruce cells with fungal culture filtrate (5 and 20% v/v concentrations) evoked an increase in the total contents of phenolic acids (represented by the sum of free, methanol soluble ester- and glycoside-bound phenolics and methanol insoluble cell-wall bound phenolic esters). The challenge with filtrate was in particular manifested in the increase (compared with the control) in the contents of cell wall-bound phenolic acids (by about 100 and 130% in 5 and 20% filtrate, respectively) and soluble phenolic glycosides (by 37 and 65% in 5 an
