Northern red oak (Quercus rubra L.) as a species suitable for the upcoming seasons with frequent dry periods


Northern red oak (Quercus rubra L.) has higher tolerance to dry periods and to lower soil nutrient content. It seems to be more resistant to tracheomycosis and therefore it should be considered as a promising species on selected forest sites. The research plots are situated in the Louny region with significant rainfall deficit; good model area for future expected climatic changes. New plantation of northern red oak and sessile oak on together 10 subplots with 500 plants were measured between 2015 and 2019. Results proved significant level (α = 0.05) of better height growth of northern red oak as well as higher resistance to dry periods (lower mortality). Lang’s Rain Factor proved to be a good indicator of difficult climatic condition during growing seasons and therefore could be used for realistic evaluation of possible success or failure of artificial regeneration.
