The aim of the present study was to develop allometric equations for predicting aboveground biomass of Norway spruce (Picea abies (Linnaeus) H. Karsten) applicable to the typically managed spruce forest on acidic and nutrient-medium sites in the Czech Republic. The models were based on an extensive ...

AbstractFull Text

Wood density, tracheid length and growth rate were measured in Aleppo pine scions, 21-23 years old, and in Brutia pine rootstocks. In regard to the relationship between cambial age and dry density the results showed that the density increased with cambial age in both scions and rootstocks while the ...
