    • Comparative evaluation of preservation and growth of spruce climatypes based on long-term provenance trials in Russia 

      Nikolaeva, Marina A.; Faizulin, Danial Kh.; Potokin, Alexander Ph. (Instytut Badawczy Leśnictwa, 2014-03)
      The article presents the results of provenance trials carried on the Norway spruce (Picea abies (L.) Karst.), the Siberian spruce (Picea obovata Ledeb.) and hybrid forms of these two species. The trails were laid in 1977–1978 ...
    • Estimating the growth of 20- to 26-year-old lodgepole pine plantations in the Leningrad region of Russia 

      Zhigunov, Anatoly V.; Butenko, Оlesia Y. (The Committee on Forestry Sciences and Wood Technology of the Polish Academy of Sciences and the Forest Research Institute in Sekocin Stary, 2019-03-15)
      The aim of our study was to compare the growth rates of lodgepole pine (Pinus contorta Dougl.) with those of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L.) in plantations. The experimental plots were ...
    • Fast and cheap identification of elite aspen clones in the North-West of Russia using ISSR markers 

      Zhigunov, Anatoly V.; Shabunin, Dmitrii A.; Butenko, Olesia Yu.; Lebedeva, Marina V (The Committee on Forestry Sciences and Wood Technology of the Polish Academy of Sciences and the Forest Research Institute in Sekocin Stary, 2018-12-15)
      In 2001–2006, several experimental aspen plantations were established in the North-West of Russia (Leningrad region). Three in vitro propagated elite aspen (Populus tremula L.) clones from the Kostroma Forest Research ...
    • Nature-oriented potential resource and melliferous value of forest belts in steppe agro-forest landscapes 

      Samsonova, Irina; Gryazkin, Anatoly; Belyaeva, Natalia; Belyaev, Vladimir; Petrik, Vitaliy; Bespalova, Veronica; Lyubimov, Alexander (The Committee on Forestry Sciences and Wood Technology of the Polish Academy of Sciences and the Forest Research Institute in Sekocin Stary, 2018-03-15)
      Creation of forest shelterbelts in steppe zone is important because they allow to obtain the highest yields of grains of cereals where the area of the most favorable conditions for growth is formed in comparison with many ...
    • Rural forested areas as an only background for regional carbon and environmental balance 

      Alekseev, Alexander (Instytut Badawczy Leśnictwa (Forest Research Institute), Komitet Nauk Leśnych PAN (The Committee on Forestry Sciences of the Polish Academy of Sciences), 2009)
      Techno systems release CO2 meanwhile natural ecosystems accumulate it in biomass and these flows for total techno-ecosystem stability should be in quantitative balance. General environmental stability (GES) may be described ...
