LOCAL RACES OF SCOTS PINE (PINUS SILVESTRIS L.) IN POLAND,
THEIR GENETIC VALUE AND THEIR ORIGIN


Summary


The author accepted Rohmeder´s and Schonbach´s definition (1959) stating: »The
race is a population which distinguishes itself from populations of the same species
in one or more hereditary factors«.


Discussed were the works published so far and dealing with the systematics of
Pinus silvestris L. species.
From the standpoint of forest genetics there can be distinguished on the territory
of Poland the following local races of Scots Pine:
1 — North-eastern Scots Pine called Masurian Pine;
2 — Pine of the central Polish plains represented among others by the Pine cf
Bolewice;
3 — Mountain Pine growing in the relict localities in the mountains of the Ta


tra and the Pieniny.
The other local races are still little known.
Discussed were also the value and importance of these races for forestry on the


basis of the results of provenance trials.
The data of pollen analysis permit us to put forth the thesis that the Northeastern
Pine is issuing from the remote refuges which were localized during the Pleistocene.
The author explains the silvicultural value and wide ecological range of the Masurian
Scots Pine through the history of its postglacial migration and the climatic
conditions of its contemporary natural area of distribution.
