Genetic variability of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L. Karst.) natural regeneration compared with their maternal stands
Nowakowska, Justyna Anna; Zachara, Tadeusz; Konecka, Agata (Instytut Badawczy Leśnictwa, 2014-03)The genetic variability and biodiversity of tree populations ensures the stability and sustainability of forest ecosystems. New research tools based on molecular DNA markers enable precise characterization of forest genetic ... -
Growth of broadleaved species on post-agricultural lands introduced during the process of stand conversion with a use of artificial gaps
Zachara, Tadeusz (Instytut Badawczy Leśnictwa (Forest Research Institute), Sękocin Stary, Poland, 2019-12-15)This paper presents results on the restoration of Scots pine stands established on post-agricultural lands undergoing conversion into mixed stands. Sessile oak (Quercus petraea), common beech (Fagus sylvatica) and ... -
The influence of different thinning methods on dominance coefficients of future crop trees in even-aged Scots pine stands
Zachara, Tadeusz (Instytut Badawczy Leśnictwa, 2014-03)The research aim was to evaluate the influence of different thinning methods on future crop tree growth. Investigations were conducted on permanent Scots-pine experimental plots, established in 1960s and 1970s in Kozienice, ... -
Ways to use silver birch Betula pendula Roth regeneration in sites considered for stand conversion due to decline of Norway spruce Picea abies (L.) H. Karst. in the Silesian Beskid Mountains
Ambroży, Sławomir; Zachara, Tadeusz; Kapsa, Mariusz; Chomicz-Zegar, Elżbieta; Vytseha, Ruslan (Instytut Badawczy Leśnictwa (Forest Research Institute), Sekocin Stary, Poland, 2017-09-15)One of the tree species appearing after a decline of Norway spruce Picea abies (L.) H. Karst. in the Silesian Beskid Mountains is Silver Birch Betula pendula Roth. Therefore our study was aimed at evaluating this birch ...
