The seasonal growth rhythm and frost hardiness development of Norway spruce (Picea abies (L.) Karst.) in Northern Sweden were characterised in trees from local seed sources and transferred seed sources of natural and selected origins. The main aim was to clarify whether the growth performance of selected populations of local origin had a similar physiological basis to the growth performance of southern natural populations. Populations of southern origins tended to initiate growth and dehardening later in spring, and start growth cessation and hardening later in autumn, than populations of northern origins. Populations transferred more than approximately 3 deg in latitude showed poor growth performances due to lower numbers of stem-units. S...
