Morphophysiologic traits of spruce trees in conditions of Izhevsk

Data on the condition of Picea genus (spruce) representatives in an urban environment have been analyzed. The viability under different environmental conditions and stand types is evaluated. The relative viability of forest stands is evaluated. Morphogenic traits of conifers are examined for the annual increment development. The photosynthetic pigments dynamics is tracked for two coniferous plants across various forest types, including park forests, roadside hedgerows, and plantings in the residential area. The specific responses of pigment system to the urban environment have been revealed for the two coniferous plant species. We have found an increased concentration of carotinoids and higher resilience of blue spruce (Picea pungens Engelm.) in an urban environment.
