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. 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.

V diplomski nalogi smo analizirali priraščanje bukve (Fagus sylvatica L.) v odvisnosti od rastiščnih razmer. Vse meritve so potekale jeseni 2014 na območju Leskove doline. V okviru naloge smo postavili, 12 ploskev na katerih je prevladovala bukev. Ploskve smo poiskali na treh različnih reliefnih tipih: vrtača, pobočje in greben. Vsakemu drevesu je bila izmerjena višina, prsni premer (1,3 m od tal) in določen položaj na ploskvi. Poleg tega smo odvzeli vsem analiziranim drevesom na prsni višini tudi izvrtek za zadnjih 10 let priraščanja. Devetim dominantnim drevesom bukve so bili odvzeti izvrtki do stržena. Rezultati so pokazali, da imamo najvišje lesne zaloge v vrtačah. Povprečni radialni in relativni temeljnični prirastek s starostjo dreves upadata. Radialni prirastek prej kulminira kot relativni temeljnični prirastek. Ugotovili smo, da imajo drevesa med 200 in 300 leti starosti v povprečju konstantne prirastke, ki skorajda ne upadajo. Podraslo drevje ima nižje radialne prirastke, toda najvišje relativne temeljnične prirastke. Pobočja imajo najvišje radialne in tudi relativne temeljnične prirastke. S povečevanjem oddaljenosti med drevesi narašča povprečni radialni prirastek dreves, temeljnični prirastek sestoja pa ne. In this thesis, we analyze the increment of beech (Fagus sylvatica L.) depending on site conditions. All measurements were carried out in autumn 2014 in the area of Leskova Valley. In the context of the tasks we set up 12 plots dominated by beech. Plots were established on three different types of relief: sinkholes, slopes and ridge. For each tree its height, breast diameter (1.3 m from the ground) and a geoposition on the surface was measured. In addition, for all analyzed trees at breast height the increment core for the last 10 years was taken. Nine dominant beech tree were drilled to the pith. The results showed that we have the highest growing stock in sinkholes. Average radial and relative basal area increment are declining with age of trees. Radial increment culminates sooner as the relative basal area increment. We have found that trees between 200 and 300 years of age have on average constant increments, which hardly decline. The suppressed trees have lower radial increments, but the highest relative basal area increments. The slopes have maximum radial and relative basal area increments. By increasing the distance between the trees an average radial increment of trees increases, while the basal area increment does not.
