Improvement of pre-sowing treatments for dormant, European beech seeds

Submitted by Zuzana Vondráková on Tue, 02/13/2018 - 16:24

Annotation: 

The overall goal of the project is to determine the factors responsible for the inefficiently of existing, pre-sowing treatments so that beechnut germination and subsequent emergence of beech germinants can be improved. The results will be used to develop protocols for providing better and more economical use of beechnuts including field emergence and for obtaining sufficient quantities of seedlings for reforestation.

Effect of UV-B radiation on polyamine metabolism and accumulation of hydroxycinnamates and flavonoids in Norway spruce

Submitted by Milena Cvikrová on Tue, 02/13/2018 - 16:22

Annotation:

The aim of the project was to evaluate the alterations in polyamine biosynthetic enzymes and polyamine contents and the levels of hydroxycinnamic acids and flavonoids after the exposure of embryogenic tissue cultures of Norway spruce to UV-B radiation. Histochemical tests for the presence of polyphenolic substances (with UV-B protecting character) on embryo sections completed the biochemical analyses.
