Features of phenological development and adaptation of Siberian larch in the conditions of European Northeast

Results of studying the phenological development of Larix sibirica Ledeb in north environmental condi-tions (Republic Komi) are resulted. On the basis of long-term researches the ecological-biological char-acteristic of a kind is given. A number of the correlation equations of communication for forecasting the approach periods of coming phenodate on previous phenodate phases is calculated. Results of studying the adaptable possibilities and frost resistance of plants are stated. Authentic connection between indica-tors of seasonal development of a larch and its damageability at low temperatures is established. The as-sociativity of seasonal development dynamics of a siberian larch with dynamics of year phenophases in the conditions of middle taiga subzone is revealed.
