The cytogenetic parameters of Pinus sylvestris L. under conditions of the Far North of Russia (Karelia)
The cytogenetic analysis of the Pinus sylvestris L. seed progeny in the forests of the northern taiga in the Far North of Russia conditions was carried out. Two Pinus sylvestris populations growing in Ambarnskoy and Pyaozerskoy forest divisions of Loukhsky district of Karelia Republic were studied....
