Název v původním jazyce

Republika Češka - Obnova i očuvanie posebnih formi obične smreke na području Ora planine

Popis výsledku v původním jazyce

Područje Ora planine je u nedavnoj prošlosti kroz nekoliko perioda bilo pogođeno teškim imisijskim opterećenjem oksidima sumpora. Relativna otpornost pojedinih stabla obične smreke s tog područja trenutno predstavlja osnovu za uzgojne programe usmjerene na oporavak dijela populacije obične smreke prisutne na Rudnoj gori. Provedba ovakvih programa očuvanja, između ostalog, zahtjeva provjerene tehnike vegetativnog razmnožavanja za preživljavanje pojedinačnih stabala obične smreke, odnosno njihovih ‘ex situ’ očuvanih klonova. Ovdje su iznesene kratke informacije o trenutnim istraživačkim aktivnostima usmjerenima na očuvanje i razmnožavanje ekotipa obične smreke prisutnog na Rudnoj gori u okvirima nastojanja da se ovaj ekotip vrati na izvorne lokalitete nakon spomenutog razdoblja velikih onečišćenja ovog planinskog područja u Republici Češkoj. Predstavljeno istraživanje bavi se pokušajima razvoja metodologije vegetativnog razmnožavanja starijih stabala obične smreke, reznicama i cijepljenjem, što proizlazi iz potrebe da postojeće metode vegetativnog razmnožavanja obične smreke postanu učinkovitije. Na taj način bi se mogao koristiti biljni materijal dobiven od starijih stabala u subpopulacijama.

Název v anglickém jazyce

Czech Republic - Recoveration and preservation of specific forms of Ore Mountains Norway spruce

Popis výsledku anglicky

The relative resistance of some Norway spruce tree individuals, which for a long time rarely survived during several periods of heavy imission load in the recent past, in the Ore Mountains area in places damaged by imission (sulphure oxides imission pollution), presented the basis for breeding programs aimed at recovering a partial population of Ore Mountains ecotype of Norway spruce in current time. Implementation of such rescue programs requires, among others, the use of proven vegetative propagation technology for surviving Norway spruce individuals, respectively their ex situ conserved clonal variants. There is presented brief information about some current research activities aimed to preservation and reproduction of Ore Mountains Norway spruce ecotype in frame of this ecotype repatriation back to Ore Mountains localities of its origin, after above mentioned period of big imission damages of these mountains area in the Czech Republic. Presented paper deals about attempts to develop the methodology for vegetative propagation of older donor Norway spruce trees by cutting and grafting, which comes out of the need to make current methods of Norway spruce vegetative propagation more effective, so that material derived from older source individuals of sub-populations of this tree can be used.
