Morphological differentiation of cones of several Picea species from Europe and Asia


, : Morphological differentiation of cones of several Picea species from Europe and Asia. Wiadomosci Botaniczne 37(3-4): 11-12

The studies were made on population samples of cones from five species of Picea A. Dietr. included in the subgenus Picea occurring in the boreal, sub-boreal, and Mediterranean part of Eumsia. There are: P. abies (L.) Karst., P. obovata Ledeb., P. koraiensis Nakai and P. orientalis (L.) Link. from section Picea, and P. omorica (Pancic) Purk. from section Omorica. Ten characters were analysed altogether and these were described with the help of arithmetical means. In the studies numerical data obtained by other authors were also utilized. Arithmetical means of characters for general samples of species of for local population samples were compared mutually according to the Jentys-Szaferowa graphical method. Complete results of studies are already published.
