Abstract
The article presents the results of investigation of seeds characteristics and growth indicators of 2-year-old Douglas fir seedlings of different geographical origin in the conditions of Central and North-Eastern Ukraine. Douglas Fir seeds were received from USA in summer 2012. Their size, color and weight were determined. The influence of natural conditions of seed harvesting regions on its weight was detected by correlation analyses. The growth indices of 2-year old seedlings grown in greenhouses in Kharkiv and Kyiv regions were analyzed. In Boyarka Forest Research Station, the dependence between provenances growth rates and latitude and longitude of stand locations where seeds had been harvested were revealed. The best growth provenances for Ukraine were preliminarily defined.
