Analiza uspešnosti saditve listavcev na posekah v sestojih črnega bora (Pinus nigra Arnold) pri Divači

Leskovec, Lea (author), Roženbergar, Dušan (mentor)

Na Krasu v okolici Divače je bilo leta 2012 na dveh rastiščih osnovanih 6 poskusnih ploskev s sadikami šestih različnih avtohtonih vrst listavcev: navadnega koprivovca (Celtis australis L.), gradna (Quercus petraea (Matt.) Liebl), navadne bukve (Fagus sylvatica L.), divje češnje (Prunus avium L.), navadnega oreha (Juglans regia L.) ter gorskega javorja (Acer pseudoplatanus L.). Z namenom ugotavljanja primernosti drevesnih vrst so bile sadike s to diplomsko nalogo po štirih letih znova popisane; izmerjena je bila njihova višina, premer 5 cm nad tlemi, dolžina terminalnega poganjka ter ocenjena vitalnost in kakovost. Skupno je preživelo 56 % vseh posajenih sadik. Kot najuspešnejša vrsta se je z najvišjim deležem preživetja (72 %) in največjo povprečno višino ter premerom izkazala divja češnja. Visok delež preživetja je imel tudi navadni koprivovec (71 %). Kot najbolj kakovostne in vitalne so bile ocenjene sadike bukve, ki pa je imela najnižji delež preživetja (13 %). Kakovost rastišča je imela največji vpliv na merjene parametre pri bukvi, gorskem javorju in orehu, najmanjši pa pri gradnu.

Abstract

In the year 2012, six research plots were based near the town Divača in the Karst region. The following tree species were planted on all plots: European nettle tree (Celtis australis L.), sessile oak (Quercus petraea (Matt.) Liebl.), common beech (Fagus sylvatica L.), wild cherry (Prunus avium L.), common walnut (Juglans regia L.), and sycamore (Acer pseudoplatanus L.). To find out which species are the most suitable for conversion, we repeated the measurements after four years. 56% of all seedlings survived. The most successful species was P. avium with the highest survival rate (72%) and the highest average seedling height and stem diameter. C. australis also had high survival rates (72%). F. sylvatica seedlings, which had the lowest survival rate (13%), received the highest quality and vitality assessments. Field conditions had the greatest impact on the measured parameters in F. sylvatica, A. pseudoplatanus, and J. regia, and the least in Q. petraea.
