Serbian Spruce is as Vulnerable as Sitka Spruce to Damage by the Sitka Spruce Weevil
Western Journal of Applied Forestry, 1992Abstract Serbian spruce (Picea omorika) was first damaged naturally by the Sitka spruce weevil (Pissodes strobi) at about 15 years of age in an area on Vancouver Island where this weevil commonly attacks Sitka spruce (Picea sitchensis).

Somatic embryogenesis, the process in which embryos, similar in morphology to their zygotic counterparts, are induced to develop in culture from somatic cells, is a suitable model system for investigating the regulation of embryo development. Through this process, a large number of embryos at defined stages of development can easily be obtained ...

Afforestation of Lutz Spruce, Sitka Spruce, and Norway Spruce in the Vesteraalen Islands, Norway
1993Tree species from Alaska and Canada have been used for afforestation in northern Norway since the late 1920s. Afforestation projects were small in the beginning because the performance of foreign species far north of their natural range was unknown.

Norway spruce and spruce shoot aphid as indicators of traffic pollution
Environmental Pollution, 2000Two-year-old Norway spruce (Picea abies (L.) Karst) seedlings were exposed to traffic emissions along roadsides with three different traffic densities and speed limits; highway, street and a quiet local road. The responses of the exposed seedlings as a host plant and those of spruce shoot aphid (Cinara pilicornis Hartig) were studied.

Inheritance of plastids in interspecific hybrids of blue spruce and white spruce
Theoretical and Applied Genetics, 1989Chloroplast DNA (cpDNA) was purified from blue spruce (Picea pungens Engelm.) and white spruce [P. glauca (Moench) Voss], and was digested with several different restriction endonucleases. Restriction fragment length polymorphisms (RFLPs) were identified that differentiated the cpDNA of both species.
