3 Conclusion
Selected phenophases entrance is generally started at first in FLV I and it is observed later in
higher FVL; the need of degree-days total of daily air temperature above 0 ºC is falling from
first to fifth FVL, exceptions existed and they are noted. Microclimate and exposition of forest
stand plays important role.
