Variability of seed germination and germination energy from Canadian provenances of Douglas fir

Abstract

Tests with seed and seedlings, is among the first experiments in complex system of comparative research conducted in addition to introduction. This paper presents the results of research of the seed germination and germination energy from 14 Canadian provenances of Douglas fir, originated from 49° 10' to 51° 35' latitude, and from 600 to 1070 m altitude. Knowledge about variability of investigated parameters of seed quality, is of great significance for knowing about genetic potential of selected provenances, as one of essential parameter for introduction of Duoglas fir on suitable sites in Serbia.
