Form diversity and health condition of norway spruce (Picea abies (L.) Karst.) in the main forest types of Ukrainian Carpathians
Journal Title: Лісівництво і агролісомеліорація - Year 2014, Vol 125, Issue
Abstract
The study of the Norway spruce health depending on its morphological forms in the main types of the Norway spruce forests in the region of the Ukrainian Carpathians (19 objects) showed that the health condition of all surveyed forms improved for the follows main forest types: wet pure Norway spruce mesotrophic forest type, wet Common beech-Silver fir-Norway spruce mesotrophic forest type, wet Common beech-Norway spruce-Silver fir mehatrophic forest type, wet Common beech-Norway spruce-Silver fir mesotrophic forest type. Predominant morphological forms of the Norway spruce in the region are as follows: brown and scaly bark cover, comb type of branching and cone-shaped crown. In the Transcarpathian region, morphological forms diversity of the Norway spruce is the lowest in the region and in the Chernivtsi region it is the highest. Morphological forms diversity of the Norway spruce is homogeneous only in the wet Common beech-Silver fir-Norway spruce mesotrophic forest type within main forest types and reliable relationship between Norway spruce forms and forest types were not found. Norway spruce trees with brown-gray bark, with fissured bark, with brush branching and with conical or pyramidal crown have the best health conditions, but this pattern is not always reliable for different forest types and natural zones. All surveyed forms have the best health conditions in the wet Common beech-Norway spruce-Silver fir mesotrophic forest type, worst for the bark color and for the type of branching in the wet pure Norway spruce mesotrophic forest type, and for the bark cover and for the shape of the crown in the wet Common beech-Silver fir-Norway spruce mesotrophic forest type. Reliable correlations between the Norway spruce form diversity and the health conditions were not found in the region (r ≤ |0,42|). Local morphological forms of the Norway spruce are recommended for the Norway spruce forests growing.
