Zgradba, rast in produkcijske sposobnosti sestojev cera v Suhi Krajini : diplomsko delo - visokošolski strokovni študij - 1. stopnja

Škufca, Nejc (author), Kadunc, Aleš (mentor)

V okviru diplomske naloge se je analiziralo zgradbo, rast in produkcijsko sposobnost cerovih (Quercus cerris) sestojev v Suhi krajini. V ta namen se je postavilo šest ploskev velikosti 30 x 30 m. Na njih se je analiziralo zgradbo sestoja. Devet najdebelejših dreves (cera) se je posekalo in izvedlo debelno analizo. Pokazalo se je, da cer prevladuje v temeljnici sestoja ter se nahaja predvsem v strehi sestoja. Večina krošenj je asimetričnih ali majhnih. Rast cera in produkcijska sposobnost sta višja na rastišču Hedero-Fagetum kot na rastišču Querco-Carpinetum. Rastiščni indeksi pri starosti 100 let (SI100) se gibljejo med 18 in 30 m. Višje poletne temperature negativno vplivajo na širino branike v tekočem letu. Tudi višje zimske in spomladanske temperature imajo pogosto podoben učinek. Pomembnejšega vpliv padavin nismo potrdili.

Abstract

In the present study stand structure, growth and productivity of Turkey oak (Quercus cerris) in Suha krajina were analysed. For this purpose six research plots measuring 30x30 meters were set. On the plots stand structure was analysed and nine thickest trees (Turkey oaks) were cut and stem analysis was carried out. It turned out, that Turkey oak prevails in stand basal area. It is present above all in stand canopy. The majority of crowns are asymmetric or small. The growth of Turkey oak, and productivity as well, is higher on siteHedero-Fagetum than on site Querco-Carpinetum. Site indices at age of 100 years (SI100) are between 18 and 30 meters. Ring width is negatively influenced by higher summer temperatures in current year. Higher winter and spring temperatures have similar effects frequently. The precipitations did not turned out as an important factors regarding radial growth.
