Use of the Hairiness Character of Young Shoots for Identification of the Species of the Genus Picea A. Dietr.
O. N. POTEMKIN
Abstract
In 24 populations of the Siberian spruce (Picea obovata Ledeb.), 14 populations of Yeddo spruce (Picea ajanensis (Lindl. et Gord.) Fisch. ex. Carr. and 5 populations of Korean spruce (Picea koraiensis Nakai.), polymorphism of hairiness of young shoots - one of the main characters for identification of independent spruce species - has been studied. Dependence of variation of this character on the geographical conditions of the population habitat has been found. Due to the high level of polymorphism of the character, it is recommended not to use it as a diagnostic when defining spruce species.
