VARIABILITY OF PHYTOMASS COMPONENTS IN CONTRAST ORIGINS OF GEOGRAPHICAL CULTURES OF THE PINE IN THE NOVOSIBIRSK REGION
The main method of studying of geographical variability of hereditary properties of forest species is the creation of geographical cultures that is cultivation and comparative assessment of seed progeny of different geographical origin. On the results of studying of these cultures it is possible to identify the climatypes, suitable for cultivation in the test area, and to detail forest seed zoning.
