Povzetek
V diplomski nalogi smo analizirali priraščanje smreke (Picea abies) v odvisnosti od rastnih razmer. Na 12 ploskvah smo izmerili drevesa in pridobili izvrtke za zadnjih 10 let ter izvrtke do stržena za dominantna drevesa. Izvrtke smo nato analizirali s pomočjo programa WinDENDRO. Lesna zaloga je bila najvišja v vrtači, najnižja pa na pobočju. Na večini ploskev je bila variabilnost starosti in drevesnih dimenzij zelo velika. Radialni in temeljnični prirastek smo analizirali za obdobje 5 let ter 10 let. Z večanjem prsnega premera (1,3 m od tal) se 10-letni radialni prirastek povečuje, s starostjo pa zmanjšuje. 10-letni temeljnični prirastek se povečuje z večanjem prsnega premera. S starostjo dreves in z večjo povprečno oddaljenostjo med drevesi na ploskvi pa se zmanjšuje. Podraslo drevje ima nižje prirastke, prav tako drevje na pobočjih v primerjavi z vrtačami.

Norway spruce increment depending on the growth conditions in Leskova dolina |
Sekundarni povzetek: |
In this thesis, we analyzed the increment of Norway spruce (Picea abies) depending on growing conditions. For this pupose 12 plots were selected. On the plots the trees were measured and increment cores obtained for the last 10 years. For the dominant trees cores to the pith were taken. Increment cores were then analyzed using the program WinDENDRO. Growing stock was the highest in the sinkholes and the lowest on slopes. On most plots the variability of the age and tree dimensions was high. Radial and basal area increment was analyzed for a period of 5 years and 10 years. By increasing the breast diameter (1.3 m from the ground), the radial increment of the last 10 years increases, while with the age decreases. As regards basal area increment, it increases with increasing breast diameter. With the age of the trees and with a greater average distance between the trees in the plot the basal area increment is decreasing. The suppressed trees have lower increments, as well as trees on the slopes compared to sinkholes. |
