Račko, Vladimír, 1962- Tvorba bariérových zón buka (Fagus sylvatica L.) indukovaných poranením = Formation of barrier zones of beech (Fagus sylvatica L.) inducted by injury / Vladimír Račko, Oľga Mišíková. -- Obr., tab. -- Lit. - The effect of different injury periods and tree species composition of beech stands on change the structure of the barrier zone of xylem formed after injury was studied in this work. Findings at microstructure level confirmed significant differences in the structure of barrier zones and new xylem formed after injury. A strong barrier zones are formed in wounds originated in the middle growing season. However, barrier zones formed in wounds originated in the beginning and end of the growing season were narrower or interrupted, or not originated at all. In the wounds originated at the middle of dormant period were formed quite wide however short barrier zones. Also, microstructure of xylem formed after injury was different than microstructure formed before the injury. It was characterized by reducing the vessel diameters and increasing the proportion of fibers and simultaneous increase of the thickness the parenchyma rays. The results confirmed the significant impact of both observed factors on the differences in the ability to protect the cambium against infection and damage by pathogens. - Cieľom článku bolo vo väzbe na obdobie vzniku poranenia počas roka (začiatok, stred, koniec vegetačného obdobia a obdobia vegetačného kľudu) popísať zmeny v tvorbe a štruktúre novotvoriaceho sa xylému a obranných bariérových zón.
